GERSTEL Management

Prepared for further growth

Over the past two years, we have prepared GERSTEL, readying the company for new opportunities and challenges.


Drinking Water analysis

PFAS analysis automated and miniaturized

Fully automated determination of the PFAS compounds listed in the EU Drinking Water Directive 2020/2184 is achieved by online SPE with replaceable cartridges coupled with LC-MS/MS. Just a 1 mL sample volume is required, improving both efficiency and sustainability.


GERSTEL MPS LabWorks Platform

The basis of your analytical success

Die GERSTEL MPS LabWorks Platform is  the only truly universal system GC/MS sample introduction


Food Safety

Focusing on 3-MCPD and Glycidol

When fat containing foods are processed and heated, fatty acid esters of 3- and 2-monochloropropanediol (3-MCPD and 2-MCPD), and of glycidol can be formed, all of which are unwanted process contaminants. The presence of these compounds in food must be monitored using international standard methods. Given the abundance of food and food products, monitoring should be efficient and therefore automated. GERSTEL offers a selection of validated automated analysis solutions.


Solutions for Thermal Desorption

Comprehensive and flexible analysis

In many types of analysis, both known (target) and unknown (nontarget) analytes must be determined. When monitoring product quality and acceptance, or material emissions, both volatile and semivolatile organic compounds (VOCs and SVOCs) are determined, ideally without using toxic solvents and without analyte loss or degradation. Thermal desorption (TD) is often the technique of choice. To determine unknown compounds, the TD system used must be capable of handling even difficult analytes without loss or discrimination.


Food Safety Monitoring

Ethylene oxide in the sights of food inspectors

In large numbers of sesame seed shipments, especially from India, EU food inspectors have found residues of the highly toxic compound ethylene oxide, leading to food product recalls with associated public information campaigns. Many years ago, the fumigant was widely used as a disinfectant for foodstuffs, but its use for food and feed has been strictly prohibited in the EU since 1991. To safeguard the food supply, fast, safe, and reliable analysis methods are clearly needed.


Olfactory Data Interpreter (ODI)

ODI is part of GERSTEL Enterprise Edition powered by OpenChrom.

The novel Olfactory Data Interpreter (ODI) software brings a new level of ease to data handling and interpretation of Olfactory data obtained in combination with GC/MS. Supported techniques include Cumulative Olfactogram presentation, Aroma Extract Dilution Analysis (AEDA), Sensory Panel Analysis data evaluation with Detection Frequency of each compound, as well as functions relating to extraction, cleanup, and interpretation of mass spectra.
