The PAL3 autosamplers provide high sample capacity and greater automated sample preparation capability to optimize lab productivity. The PAL3 sample injector offers options for three types of sample injection techniques for maximum flexibility: liquid injection, static and dynamic headspace, and solid phase microextraction (SPME) fiber or Arrow.
A headspace solid-phase microextraction method combined with gas chromatography mass spectrometry was evaluated for the extraction and analysis of selected pesticides, namely alachlor
A gas chromatograph (GC) is an analytical instrument that measures the content of various components in a sample. The analysis performed by a gas chromatograph is called gas chromatography. Principle of gas chromatography: The sample solution injected into
The Headspace Sampler allows introduction of volatile compounds to the GC or GC/MS from virtually any sample matrix while leaving unwanted components in a disposable sample vial. This results in less maintenance and longer lifetimes for the GC
Cannabis Market and the Increased Demand for Testing EST analytical offers Cannabis and Hemp Testing Solutions that cover a broad range of applications from accurate potency testing and terpene profiling to contaminate testing for pesticides, residual solvents, and mycotoxins/aflatoxins. We supply the sample preparation instruments, methods and experience necessary to get you up to []
Headspace GC is the preferred method for the analysis of residual solvents in actives, excipients, and drug products according to Ph Eur and USP. Accurate analysis with headspace gas chromatography requires the use of very pure solvents with extremely low concentrations of the defined residual solvents.
Sample Size 60 L Detection, UV 205 –300 nm; spectra recorded at = 210, 230, 250 and 270 nm Detection, MS API-ES, positive ion and negative ion (mass range 80 –900) Sample Preparation None, direct injection Gas Chromatography with Headspace 8 9
Our gas chromatography mass spectrometry (GC-MS) instrumentation are suited for most any applications for food, environmental, industrial and forensics analyses among others. Today's labs need and want more from their chromatography so many have turned to
Headspace vials and closures must form a tight seal for accurate analysis with reproducible results. Available in clear or amber Type I borosilicate glass with crimp or screw thread finishes. The vials are used to heat the sample until the concentration of the liquid and gas phases are in
By using the gas chromatography tech-nology, but with no need for sample preparation, milling and processing by expert lab technicians, the PETes AA Analyzer can analyse the entire preform in a fully automatic manner. It is simple to use, rapid, and it provides
