Our annual review of new high performance liquid chromatography and mass spectrometry instruments, chromatography data systems (CDS), and related products, including a summary of their significant features and user benefits.

This installment describes new high performance liquid chromatography (HPLC) and mass spectrometry (MS) instruments, chromatography data systems (CDS), and related products introduced at Pittcon 2020 or during the prior year. It summarizes their significant features and user benefits.


The Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy (Pittcon) is one of the world’s largest conferences on laboratory science. The 71st Pittcon was held at McCormick Place in Chicago from February 29 to March 5, 2020, a week before to the semi-shutdowns of Europe and North America from the spreading Covid-19 virus. Chicago has been the most frequent venue for Pittcon in recent years, with previous Pittcons held in Chicago in 2014 and 2017, in a three-year rotation. Chicago is an industrial, agricultural, financial, transportation, and communication center, as well as the third largest city in the Unites States. The city has 2.7 million residents, and the Greater Chicago area boasts a population of 9.5 million. Chicago is home to 69 of the 1000 most prominent companies in the United States, which include Boeing, Abbott Laboratories, Caterpillar, and Kraft Foods. Nevertheless, one potential issue for this location is the unpredictable weather of this midwestern city near the Great Lakes in early March. We were lucky this year with moderate temperatures and no precipitation, though the meeting attendance was reduced because of travel bans related to Covid.

The technical program remained strong this year with more than 200 technical sessions, plenary lectures, and invited, contributed, or award symposia, as well as workshops, posters, and networking sessions, and approximately 90 short courses. The 3-day exposition, however, was visibly smaller than in the past, with the number of exhibitors from the United States dropping from 630+ in prior years to about 400. The number of international exhibitors was also dramatically reduced due to the travel bans from China and many European countries (1).

New HPLC, MS, and Chromatography Data System (CDS) Product Introductions
for 2019–2020

Although introductions of new ultrahigh-pressure liquid chromatography (UHPLC) systems appear to be slowing down (1,2), manufacturers are turning their attention to HPLC system extensions and chromatography data systems (CDS), as well as mass spectrometers for liquid chromatography–
mass spectrometry (LC–MS) or direct liquid and solid sampling.

Table I lists new products, ordered alphabetically by vendor, that were introduced at Pittcon 2020 or in the prior year, followed by descriptions and commentaries of each product, categorized as systems, modules, CDS, MS, software, or accessories.

Summary and Commentary

Pittcon 2020 will be remembered as the chemistry conference which squeaked in just before more severe measures were taken in North America and Europe to combat the spread of the devastating coronavirus Covid-19. Less than a week later, the World Health Organization declared the spreading virus a global pandemic, and U.S. President Trump announced a state of national emergency for the United States. The country was in a semi-shutdown with travel bans, school closings, and indefinitely cancellation of all major public gatherings. The American Chemical Society (ACS) National Meeting in Philadelphia for late March was canceled, and the Analytica Conference in Munich was postponed from March to October. Still, Pittcon did suffer significantly from many cancellations of exhibitors and conferees, resulting in lower attendance and fewer exhibitors.

One disturbing trend unrelated to the coronavirus was the skipping of Pittcon this year by two major manufacturers (Waters and Thermo Fisher Scientific). Although Pittcon, as a premier event for new product introductions, has been declining in size in recent years as a result of competing conferences and other communication channels, it remains the largest general analytical chemistry conference in North America with global draws for buyers and sellers alike. It is my opinion that skipping Pittcon is a drastic and unpopular move in the eyes of many conferees who wish to compare new products on the exhibition floor. The opportunities to meet with friends and colleagues, learn new technologies, and see new instrumentation on the exhibition floor are what inspire many analytical chemists to come back to Pittcon year after year.

This installment summarizes new HPLC and MS products introduced at Pittcon 2020 and during the prior year and describes the pertinent features of these products. Personally, this is my 19th consecutive year of giving Pittcon HPLC short courses, which had a record attendance of 44 this year. My busy schedule included attending symposia, networking sessions, and the exhibition, interspersed with many meetings and social events, such as board or dinner meetings of LCGC and the Chinese American Chromatography Association (CACA), the Separation Community Mixer of the Chromatography Forum of the Delaware Valley, and the Pittcon Party at the Museum of Science and Technology.

In this unusual time of severe disruptions of conferences and travels, we are all hopeful that the world will survive the calamity and that our analytical chemistry community will return to some normalcy for Pittcon 2021 in New Orleans.
