Analytical Vials. Vials play a significant role in analytical analysis and result reproducibility. Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified, application-specific, contaminant-free vials can significantly reduce risk. We offer a broad spectrum of Supelco ® products including
Gas chromatography-flame ionization detector (GC-FID) analysis The GC analysis of an EO solution in hexane (dilution ratio 1:200 v/v) was carried out using an Aijiren 4890N instrument equipped with a FID and an HP-5 capillary column (30 m × 0.25 mm, film thickness 0.17 μm). The column temperature program was the same as described for the HP5

Jan 01, 2020 · 1,2-DCB was quantified in each test using a calibration curve. To generate the calibration curve, we prepared 0, 25, 50, 100, and 200 ppb of 1,2-DCB solution in a 2-mL amber GC vials using methanol as the solvent. IS (500 ppb) was added on each vial. Next, we injected 1 µL of each solution into a clean TD tube and analyzed it using TD-GC/MS.

for GC analysis [10,14,18–20]. One study used a simple GC/MS method (no derivatization) for the confirmatory analysis of 17a-trenbolone and 17b-trenbolone in an agricultural receiving water, though with very poor sensitivity and variable performance [10]. However, no gas chromatography–mass tandem spectrometry
