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).
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.
New UHPLC systems introductions have slowed in the last couple of years as manufacturers have appeared to focus more on HPLC line extensions and customized systems for specific applications (1).
Agilent offers a new extension to its InfinityLab Purification Solutions with the Agilent 1290 Infinity II Preparative Open-Bed Sampler/Collector. This instrument combines analytical and preparative tasks in one instrument, to allow analytical-scale compound isolation through preparative-scale purification from a few milligrams to multiple grams of material. It has the unique capability to sample from any position of the fraction collector and allow purification and fraction reanalysis to be combined and homogenized before reinjections.

The marketing landscape for mass spectrometry (MS) instruments has been described elsewhere (1). There is no slowing down of new MS introductions this year as manufacturers continued to upgrade their product offerings in high-resolution, hybrid, and tribrid MS-such as time-of-flight (TOF), quadrupole-TOF (Q-TOF), and orbital trap systems. Also, there are more offerings in compact MS instruments with unit resolution such as single-quadrupole (SQ), triple-quadrupole (TQ), and ion-mobility MS (IMS) (1,3). There are also newer startup companies focusing on unique application systems such as analyzers for fermentation media or solid sampling.
The Rebel from 908 Devices is an integrated online MS analyzer for fresh and spent media analysis in the biopharmaceutical industry. It is capable of a 7-min assay of 32 analytes (amino acids, bioamines, vitamins, dipeptides) with a 10-µL sample volume. The system is good manufacturing practices (GMP) compliant and can include automated sample preparation steps such as filtration and dilution.
One of three new MS systems introduced by Agilent Technologies in 2019–2020, the iQ is a compact single-quadrupole mass selective detector (MSD) for HPLC with auto data acquisition and reporting in auto-acquire mode, which automatically establishes optimal MS parameters with automatic tuning. The instrument can also help with maintenance tasks through its ability to track instrument health. It can be controlled by OpenLab CDS or a simpler open-access software.
