Major Products/Service0073

MAESTRO Software: Operates Gerstel modules and systems independently or available as integrated solutions with Agilent ChemStation/MassHunter, LECO ChromaTOF, AB Sciex Analyst®, Thermo Scientific Xcalibur, and others. One method and sequence table run the complete system including GC–MS or LC–MS.

MultiPurpose Sampler MPS: GC, GC–MS, LC, and LC–MS autosampler and sample preparation robot. Performs the sample preparation techniques listed below and more.

Automated DPX: Dispersive SPE technique for fast, efficient extraction and concentration of analytes.

Automated SPE: Independent of LC–MS or GC–MS or combined with sample introduction. Based on standard cartridges.

Dynamic Headspace (DHS): Concentrates VOCs from liquids or solids. Ultra-low detection limits.

Thermal Desorption System (TDS): Ultra-low detection limits for VOCs and SVOCs up to n-C40.

Thermal Desorption Unit (TDU): Highly flexible, automated analysis of up to 196 samples. Performs thermal desorption/extraction and pyrolysis.

Twister® Stir Bar Sorptive Extraction (SBSE): Ultra trace-level determination of organic compounds in liquid matrices. Up to 1000 times more sensitive than SPME.

Cooled Injection System (CIS): Universal PTV inlet for optimized GC performance. High temperature version up to 650 °C, cryostatic cooling.

Automated Liner EXchange (ALEX): For samples with a heavy matrix load.

Automated Centrifugation, Solvent Evaporation, Weighing, Filtration, Vortexing, and Bar Code Reading

Multidimensional GC with Column Switching: Complex separations using two or more columns.

Olfactory Detection Port (ODP): For GC or GC–MS; complete with voice recognition, intensity indication, and peak annotation.

Preparative Fraction Collector (PFC): For GC or GC–MS using up to six traps.


Full applications support laboratory at US headquarters near Baltimore, Maryland, and a partner applications laboratory in Chicago, Illinois. Our applications team enables Gerstel to assist customers in applying GC and LC analysis techniques to the solution of real-world challenges.
