Mass Spectrometry for pharma, biotech and research labs

Gilson VERITY 1900 MS Detector

Mass spectrometry, widely accepted as a strong tool for identifying, characterising and purifying compounds was first made known by Dr. Joseph Thompson in the early 1900s. However, the instrumentation and analysis has traditionally needed highly trained technical staff and a highly specialised lab, limiting the reach of the technology. In many cases, lab users are forced to outsource samples to dedicated facilities for MS analysis, increasing costs.

Times are changing. Mass spectrometry, once held in the bastion of specialty laboratories, is moving more into mainstream pharmaceutical, biotechnology, and academic laboratories. The power that mass spectrometry provides in the confirmation of compounds in a mixture has become valuable to many areas such as drug discovery purification. To address this shift of use to a broader, non-expert audience, many scientists and instrument companies are rethinking mass spec instrument design. With these redesign efforts, “Mass spec for the masses” (1) has moved from concept to reality.

How to move mass spec mainstream

While the use of mass spectrometry in the characterisation and confirmation of drug compounds is highly valuable, it is also expensive. Pharmaceutical, biotech and chemical companies, as well as academic labs, are looking at a variety of approaches to control the escalating costs of purification during drug discovery from increasingly complex materials using mass detection techniques. First, they want to decentralise the characterisation process to reduce overhead costs. Usually, chromatographic fractions are sent to a dedicated mass spectrometry lab for further analysis. The large mass spectrometers used require specialised lab space because of their size, their system requirements, and the noise they generate. These instruments also need highly trained personnel to run them and highly trained service engineers to maintain them. For decentralisation to work, mass spectrometry instrumentation must become smaller in size so it easily fits into any chemistry lab. It also must become easier to use to increase the accessibility of the instrument to entry-level spectroscopists and other less experienced lab personnel. A push-button solution is needed that requires less formal training.

Next, companies want to decrease the cost of ownership associated with mass spectrometers. Traditional mass spectrometers use large amounts of resources such as power and nitrogen. More importantly, many issues affecting the performance of a mass spectrometer need much more involved repairs, typically requiring a scheduled visit from a field service engineer. The instrument downtime can generate delays for characterisation of samples, impacting productivity and increasing costs.

As Alessio Zammataro, Product Manager and Applications Scientist for chip-based mass detection technologies at Microsaic Systems noted, “There is higher demand for real-time techniques using less complex technologies.”

The VERITY 1900 MS Detector is easily incorporated with Gilson’s preparative HPLC systems. With a mass range of 50–800 amu and the ability to collect full scan signals and up to four SIM channels simultaneously, the VERITY 1900 MS Detector will become a powerful component of the lab workflow for both small and large molecule identification.

Mass detection power that fits in the palm of your hand

A new breed of mass detectors is currently focusing on meeting some of these needs through instrument miniaturisation. However, as Alessio Zammataro pointed out, “Smaller is a challenge,” given constraints of electronics, physiochemical laws and intellectual property.

VERITY 1900The VERITY 1900 MS Detector from Gilson offers a new approach that overcomes some of the constraints to miniaturisation. The VERITY 1900 MS Detector relies on proprietary micro-electro-mechanical systems (MEMS) technology developed by Microsaic Systems. The result is the ionchip®, a palm-sized, chip-based mass detector component that has detection power similar to the larger single quadrupole mass spectrometers. The use of the innovative chip-based mass detector helps to shrink the overall VERITY 1900 MS Detector footprint, simplifies the complexity during operation and maintenance, and offers reduced cost of ownership so the instrument can easily be accommodated in a non-specialised lab. The VERITY 1900 chip-based mass detector, through integration with Gilson’s TRILUTION LC software or Glider Prep software, can be programmed by simply entering in one or many target masses. Gilson’s robust and proven HPLC systems do the rest, collecting fractions based on this simple target, which makes the system easier to use by less experienced lab personnel. As Thomas Rawlins, Associate Product Line Manager at Gilson summarised, “At Gilson, we know that scientists want to produce verifiable data in a comfortable laboratory environment. In partnering with such an innovative company (Microsaic Systems), we can enable any chemist to verify the molecular weight of their analyte of interest without disrupting their quality of life in the lab.”

Parallel analysis shortens drug development times

In a traditional drug purification workflow, preparative liquid chromatography (LC) fraction collection is typically monitored by optical methods such as ultraviolet/visible light (UV/VIS). However, UV/VIS is limited and uncertainty usually exists over the exact contents of a fraction and the purity of the sample. This uncertainty leads to a second stage in the workflow: precise identification of the compound(s) in the fraction and their purity through single quad mass spectrometry at a separate specialised lab. This second phase results in additional time and money.

By adding the VERITY 1900 MS Detector to the drug purification workflow, the monitoring of the collected LC fractions is done with both optical and mass detection (UV/VIS and MS) in tandem, allowing fractions to be clearly identified and the purity determined in a single step. Running the UV/VIS and MS detection in parallel eliminates the additional time required for offline mass spec analysis and the necessity for a specialised lab dedicated to that analysis. Time savings due to mass detection during the initial step allows fraction collection to be more specific, resulting in fewer fractions to process later.

The VERITY 1900 MS Detector also decreases costs associated with ownership, as it has fewer system requirements for resources such as power and nitrogen. The system is also easier to maintain (e.g., no pump oil changes are necessary), and instrument downtime is significantly reduced, improving productivity and saving money. Many routine maintenance items are also customer serviceable, eliminating the need for a service visit. If a rare performance issue arises, one usually only needs to swap in a new chip to fix the issue.


As Alessio Zammataro summed up, “What we have achieved with this product is to maintain the standard performance of a general mainframe single quad benchtop mass spec, but have reduced its running costs and footprint.” Thomas Rawlins also noted, “I am excited to offer scientists a product that really changes the way they think about MS technology. With a chip-based mass detector, the site requirements, maintenance costs, and footprint become more similar to a basic UV/VIS detector than a traditional single quad MS.” The easy-to-use single quad VERITY 1900 MS Detector with its proprietary chip-based technology frees the mass spec from a dedicated specialised lab, allowing mass detection to move into the mainstream.
