This installment highlights new high performance liquid chromatography (HPLC) systems, modules, and software that were introduced at Pittcon 2017 and during the year prior, and describes their innovative features and significant benefits.
This annual review of new high performance liquid chromatography systems and related products covers products introduced during the last 12 months. The majority of the products were launched at Pittcon 2017.
The Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy (Pittcon) is one of the world’s largest conference on laboratory science. The 69th Pittcon was held at McCormick Place in Chicago, the largest conference center in the United States, from March 5 to 9, 2017. The last time Pittcon was held in Chicago was in 2014 (and 2011 prior), and it will be there again in 2020. Note that Chicago, Orlando, Philadelphia, New Orleans, and Atlanta are the cities selected for hosting Pittcon, with Chicago in the rotation every 3 years and the others about every 6 years. This frequency makes sense since Chicago is the third largest city in the U.S. and is also an industrial, agricultural, financial, transportation, and communication center. We had great weather this year at the conference with many sunny days and spring-like temperature in the 50s.
Pittcon is impressive with ~2000 presentations, 100+ short courses, and a huge exposition with over 800 exhibitors, including over 120 new manufacturers displaying for the first time. Although the number of attendees has been dropping in recent years, registration hit 13,300 after three days. With open admission on Thursday, a total of above 14,100 was expected, which is very good news for the conference and an indication of a healthier economy and positive outlook for instrumentation. This year’s conference featured a plenary lecture by Dr. Karl Deisseroth, a professor of bioengineering at Stanford University, on insights on optogenetic proteins using electron microscopy and mass spectrometry (MS). Once again, Pittcon 2017 provided a “Mecca” for analytical chemists and a premier venue for instrument manufacturers.
The perfect marriage of ultrahigh-pressure liquid chromatography (UHPLC) and MS instruments continues to be the megatrend in chromatography in recent years (1–5), even though this is another off year for new UHPLC system introductions. With many second-generation UHPLCs debuted by all major manufacturers in prior years (2,3), this year we are seeing mostly line extensions, application-specific systems, modules (particularly new MS or MS add-ons), and software products.
Table I lists the new product introductions (arranged alphabetically by vendor name), followed by more-detailed descriptions or commentaries.

New HPLC, UHPLC, supercritical fluid chromatography (SFC), ion chromatography (IC), modules, chromatography data systems (CDS), and related software are summarized in Table I and described with more details below.
Agilent 1260 and 1220 Infinity II systems-Two years ago Agilent introduced the 1290 Infinity II LC systems. This year, Agilent completed the InfinityLab LC Series with the 1260 and 1220 Infinity II systems, all to deliver full method compatibility. Innovative 1290 Infinity II LC technology is leveraged with the 1260 Infinity II Multisampler with dual-needle sampling and Vialsampler. A larger column oven, which fits 30-cm columns and can accommodate four columns with a single switching valve, and a range of detectors are common to both systems. The 1260 Infinity II pumps have a 600-bar pressure limit and are available in either stainless steel or bioinert format. The 1220 Infinity II system remains an integrated 600-bar system available with an isocratic or a dual-channel gradient pump that can be paired with a manual injector or an autosampler, a variable-wavelength UV detector or a diode-array detector, and external special detectors including a mass-selective detector. All systems can be operated with Agilent OpenLab CDS Software as well as third-party software with the universal Agilent Instrument Control Framework.
Bruker Elute LC series-Bruker introduces the Elute LC series systems for LC–MS analysis: SP (700 bar), UHPLC (1300 bar for ultrafast analysis), OLE (for online extraction) and HT (high-throughput with the new PAL3 autosampler).
Cromite portable HPLC-Cromite introduced a handheld, portable HPLC system that consists of an isocratic pump with a 275-bar or 4000-psi pressure limit and a max flow rate of 4 mL/min, and a UV–vis detector with a light-emitting diode (LED) source that provides up to four customizable wavelengths. The system is designed with novel approaches to mobile-phase storage and sample introduction and preparation, and it includes a single-ended leak-proof column. The system weighs 2.5 lb (1 kg) and has overall dimensions of 6.8 x 3.2 x 3.4 in. (173 x 81 x 86 mm). The device can be controlled from a PC, smartphone, or tablet via Bluetooth and can be powered off a 12-VDC power supply or external battery. The company is targeting applications in education, environmental and production QC testing with this offering. Figure 1 shows an example chromatogram obtained using the Cromite portable HPLC system.

Most analytical chemists come to Pittcon for professional development and networking. My schedule this year included teaching several short courses on HPLC, UHPLC, and method development, and chairing an invited symposium on UHPLC method development in pharmaceutical analysis. My networking events included a Chrom Mixer sponsored by Chrom Forum Delaware Valley in memory of Jack Kirkland (more than 500 attendees), a networking dinner event with the Chinese American Chromatography Association (CACA) attended by more than 120 conferees (featuring a lecture by Dr. Perry Wang of the US FDA on the perfect marriage of HPLC and MS), and the annual Pittcon presidential reception, where I personally thanked many Pittcon staff and program chairs.
I spent considerable time on the exposition floor to verify information on new HPLC products for this column installment. I returned home Thursday night, slept late and woke up to find 4 inches of snow on the ground in Connecticut. We were lucky as the weather can be unpredictable in early March in Chicago, as well as the Northeast. Rumor says that next year will be the last year for Pittcon in Orlando because the vendors complained about conference attendees visiting Disney World instead of the exposition. I love Orlando because of the excellent restaurants and the warmer weather-and I plan to visit both the exposition and the theme parks.
This installment provides a brief and nonexhaustive overview of new HPLC product introductions (systems, modules, MS, CDS, software, and related products) at Pittcon 2017 and during the prior year. Readers should contact manufacturers for additional technical details. Note that new HPLC columns are covered separately in LCGC’s “Column Watch” annual review by David Bell. The opinions expressed in this installment are the author’s own and bear no reflections on those of LCGC magazine, the Pittsburgh Conference, or any other organizations.
I wish to give thanks to the marketing and editorial staff of LCGC and all HPLC manufacturers for their timely responses to my numerous requests for information. I am particularly grateful to Davy Guillarme and Szabolcs Fekete of U. Geneva, Harika Vemula of U. Missouri at Kansas City, David Van Meter from EAG Laboratories, Hernan Fuertes from Ardelyx, and Matt Mullaney from Pentec Health for their invaluable editorial and technical input.
