An overview and assessment of the latest HPLC and mass spectrometry instruments, modules, chromatography data systems, and related software.
This installment describes high performance liquid chromatography (HPLC) and related products introduced at Pittcon 2018 in Orlando, Florida, and in the year prior. It highlights new HPLC and mass spectrometry (MS) systems, modules, chromatography data systems, and other HPLC-related software and provides brief descriptions of their significant benefits and innovative features.
The Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy (Pittcon) is one of the world's largest conferences on laboratory science. The 70th Pittcon was held at the Orange County Conference Center in Orlando, Florida, February 26 to March 1, 2018. The last Pittcons held in Orlando were in the years 2012, 2010, 2006, and 2003. Future Pittcon venues will include Philadelphia, Pennsylvania; New Orleans, Louisiana; Chicago, Illinois; Atlanta, Georgia; as well as the new locations of Boston, Massachusetts and San Diego, California. Sadly, Orlando is not on the list for future events.
Orlando remains my favorite Pittcon location because of the warmer weather, friendly people, great food, and wonderful theme parks. Orlando spans a high tech corridor that encompasses numerous centers of agrochemical, biotechnology, and pharmaceutical manufacturing, and renowned universities.
This year's Pittcon continued to be impressive, with ~2000 presentations, 100+ short courses, and a large exposition, although the duration of the exposition portion was reduced from four to three days (Tuesday to Thursday). The conference featured plenary lectures by Professor Jeremy K. Nicholson (director of the United Kingdom National Phenome Centre) on precision medicines and Dr. Stefan W. Hell (Max Planck Institute, 2014 Nobel Laureate) on optical microscopy. Pittcon 2018's program was packed full of invited symposia, poster presentations, contributed and networking sessions, and social activities, including a night out to Universal's theme park.
With ultrahigh-pressure liquid chromatography (UHPLC) firmly established as the modern high performance liquid chromatography (HPLC) platform for more than a decade, all major manufacturers have already introduced the first- and second-generation UHPLC systems (1–3). In the past few years, manufacturers continued to introduce line extensions to existing equipment, such as dual-path, intermediary-pressure, and bioinert systems (4,5). This year's new introductions also appeared to be trending toward application-specific systems (for example, cannabis analysis), front ends to mass spectrometry (MS) systems, micro- and nano-HPLC systems, biopurification systems, portable instruments, preparative LC systems, and integrated HPLC systems for quality control (QC) applications. New MS systems abounded, ranging from single-quadrupole and triple-quadrupole, to quadrupole-time-of-flight (Q-TOF) hybrid MS systems. Updates to existing chromatography data systems (CDS) proliferated, as well as software products catering to HPLC method development, peak deconvolution, pharmaceutical development, and stability testing.
Table I lists more than 40 new HPLC-related product introductions (arranged alphabetically by vendor name) at Pittcon 2018 or during the prior year, followed by brief descriptions of each product, categorized under systems, modules, CDS, and software products.

ACD/Labs Luminata-The Luminata informatics software platform is designed for efficient and comprehensive management of impurity data in pharmaceutical process development that includes organized and searchable databases of analytical and chemical information. This software is intended to provide an effective impurity control strategy in new drug development and includes new visualization tools.
ChemPower OCAS software for peak deconvolution-LC–MS data can be viewed to provide two dimensions of orthogonal separations with mass-to-charge ratio as the second dimension. ChemPower Technology is a start-up chemometric software company based in Singapore that developed an online chemical analysis system (OCAS) capable of deconvoluting closely eluted peaks from various GC–MS and LC–MS data to discover the molecular identity of unknown compounds. The software can rapidly and accurately process the entire sample data set and provide a list of all the chemicals that are contained in the sample. This type of trending software may provide additional quantitative data for difficult assays (such as biomarkers and stability-indicating assays of complex pharmaceuticals) without invoking the power and tedium of 2D-LC.
FreeThink Technologies v.5.0 ASAPprime software-Stability testing tends to consume major fractions of analytical resources in many pharmaceutical laboratories. FreeThink Technologies is a software and contract research laboratory company based in Branford, Connecticut, that specializes in stability determinations and solving stability problems. ASAPprime is its flagship software platform (validated for Windows 7/8/10 environments), which is designed to allow accurate determination of the shelf life of drug substances and drug products in about four weeks. The program uses experimental data to estimate the time to hit a specification limit (based on the formation of degradants, loss of assay, or change in dissolution performance) at a range of open temperature and relative humidity conditions, then applies a modified Arrhenius equation with statistical propagation to develop a mathematical stability model for that product.
The modeling is further enhanced by the program's database of packaging options, which enables users to determine the moisture level a product is exposed to within packaging and combines this level with the moisture sensitivity from the stability modeling. The program can calculate the probability that a product will remain within its specification limits based on different time frames, initial water content, climate zones, and packaging options.
Molnár-Institute DryLab v.4.3 for HPLC method development-DryLab v.4.3 is the latest version of this popular modeling software platform for HPLC method development. The updates include enhancements for column screening, column comparison displays, and predictions for flow variations.

It includes more intuitive operation and improved peak integration algorithms and functionalities for supporting data analysis. LabSolutions Insight library screening software supports screening via full scan or multiple reaction monitoring (MRM) mode and can display library search results for multiple analytes. This platform targets applications for food safety and forensic toxicology and provides data reviews by exceptions. This type of review is most useful in HTS applications because it highlights results that appear to be out of specifications or above the regulatory limits.
S-Matrix Fusion QbD v. 9.8.0-The latest updated version of this popular HPLC method development software platform, which uses principles of QbD and design of experiments (DoE), now includes new simulation chromatogram visualization and reporting capabilities that allow users to display simulated chromatograms in real time.
Most analytical chemists come to Pittcon for learning the latest in instrumentation, attending seminars and short courses for professional development, and networking with friends and colleagues. My schedule this year included teaching a two-day short course on HPLC and UHPLC, attending several seminars (symposia, workshops, and networking sessions) and an editorial advisory board meeting for LCGC, and hosting a dinner event sponsored by the Chinese American Chromatography Association (CACA) featuring a lecture on molecular medicine by Professor Weihong Tan of the University of Florida.
I spent two days on the exposition floor verifying information on the 40+ new HPLC products covered in this installment. I stayed three extra days in Orlando to visit theme parks with my family, thereby narrowly missing the travel frustrations caused by winter storm Riley. I returned home to be confronted by two successive nor'easter storms, Quinn and Skylar, which caused extensive power outages in New England. Indeed, the weather in early March can be unpredictable in North America. Nevertheless, Pittcon continues to inspire me year after year with renewed enthusiasm for my career choice as an analytical chemist, and I continue to look forward to future venues in Philadelphia, New Orleans, and Chicago. However, I do wish that Pittcon will return to sunny Florida again one day.
This installment provides a brief overview of new HPLC-related product introductions (HPLC systems and modules, MS systems, chromatography data systems, and software and related products) at Pittcon 2018 and during the prior year. Readers are referred to manufacturers' websites and their marketing departments for additional details. Note that new HPLC columns are covered separately in LCGC's "Column Watch" annual review by Dave Bell (8). The information and opinions expressed in this installment are the author's own and bear no reflections on those of LCGC, the Pittsburgh Conference, or any other organizations.
I wish to give thanks to the marketing and editorial staffs of LCGC and all HPLC manufacturers for their timely responses to my numerous requests for information. I am particularly grateful for the invaluable editorial and technical input from Davy Guillarme and Szabolcs Fekete of the University Geneva, Wilhad Reuter of PerkinElmer, Christin Gu of Novartis, and Giacomo Chiti of Texsus SpA.
