Gilson Connect
Gilson's GX-Series Liquid Handlers, paired with TRILUTION® LH software and GEARS, can integrate with QINSTRUMENTS thermal and shaking modules. This powerful combination enables automated workflows involving heating, cooling, and agitation—ideal for redissolving compounds, kinetic testing, derivatization before SPE, and liquid-liquid extractions. Expand your system’s capabilities with precision temperature control and flexible labware support—all fully automated for increased efficiency and reliability.
Central Nervous System (CNS) depressants can introduce calm and induce sleep. Benzodiazepines are CNS depressants used to relieve anxiety, insomnia, and panic attacks. This application note discusses a simple SPE urine extraction before LC/MS-MS to confirm the presence of 15 spiked benzodiazepine analytes.
The type of pipette you use, and your pipetting technique will have a major impact on the accuracy and results of your assays. Almost every laboratory that conducts research will have a pipetting procedure that accurately measures the exact volumes when aspirating and dispensing liquids. However, if the workflow calls for pipetting dense liquids, making sure you’re using the correct pipette can ensure accuracy in your assays.
When pipetting small volumes, you'll need to take additional steps to improve your sampling accuracy. Here are five tips for improving your pipetting technique.
Manual sample preparation and treatment is a laborious process requiring constant attention in the lab. Here’s how to optimize and automate your SPE workflows.
In this application note, three glucocorticoids and three nonsteroidal anti-inflammatory drugs were detected simultaneously from horse urine using the Gilson GX-274 ASPEC® system with two step extractions and LC/MS/MS selected reaction monitoring (SRM).
Δ9-tetrahydrocannabinol and its metabolites are essential for drug testing. GC/MS is often used for quantification of Δ9-tetrahydrocannabinol, however, it is time consuming. Rapid methods that maintain the sensitivity and selectivity of GC/MS are desirable - learn more in this application note.
