Professional 20mm GC Vial Chemistry

20mm Headspace Septa Gray Butyl Stopper: (C4020-30) An economical septum for low temperature (125°C), or low-pressure applications. The Gray Butyl Stopper does not provide a PTFE barrier. This septum is not suitable for use with alkanes, benzene, chlorinated solvents or cyclohexane.

into a gas chromatograph, there will far less of the less-volatile material entering the GC column making the chromatography Figure 1. Chromatogram from direct injection of a perfume sample.

GC: Vials are most applicable with GC methods with longer run-times. The glass vials are more compatible with the strong organic solvents used to solubilize liquid samples. HPLC: When processing samples in batches of less than 50 use vials as there is little advantage using a 96-well plate as the plate capacity would not be fully utilized.

wStandard opening vials for GC and HPLC, used on instruments of Shimadzu, Varian, Gilson etc. w To meet your micro sampling needs, Aijiren has avariety of micro volume inserts with capacities and designs that can transform our vials from full-capacity to limited volume with one simple step.

the vials at room temperature (24 ± 1 C). Extractions lasting 30 min provided the optimum peak area response for most volatile components, while maximizing the number of samples that could be analysed each day. Following headspace extraction, SPME fibres were injected into the GC and remained in the GC inlet for 10 min. 2.5. GC–MS analysis

The solvent used for this study was GC-MS grade Dichloromethane bought from J T Baker. 2.2. Methods. The chemical characterization for compounds it was conducted in two phases. First, the samples were analyzed via headspace (HS) coupled to gas chromatography with mass spectrometer (HS-GC-MS) for determination of volatile compounds.
