certified by analyzing a percentage of canisters for approximately 60 VOCs using GC/MS. The batch meets cleaning requirements if the target compound concentrations are below 0.2 ppbv. Alternatively, the 100% certification (i.e., individual certification) process is typically required for ambient and indoor air applications driven by risk

Jun 02, 2017 · Mineral oil would probably interfere with the DRO pattern especially the heavy hydrocarbon end of things. If you don't have many samples I have done blow down by using 40ml voa vials to hold the solvent and using a needle attached to a line from a regulator or compressed air line to blow into the top of the vial.

detector (GC-NPD) and/or a mass selective detector (GC-MSD). The GC-NPD provides a presumptive identification of drug compounds in blood based upon their relative retention times whereas the GC-MSD will provide a qualitative identification. The resulting data is utilized to base the selection of the confirmatory analysis method. 3.3.2.2 SCOPE

Solid Phase Extraction (SPE) cartridges provide a fast and efficient sample clean-up and concentration prior to analysis through GC, HPLC, and/or other instrument methods. SPE method concentrates and purifies analytes from solution by absorption onto a disposable solid phase cartridge, followed by elution of the analyte with a solvent

InertSep GC-e cartridges are packed with graphite carbon which has similar physical properties to InertSep GC. InerSep GC-e provides the same extraction performance as InertSep GC at low cost.

Specializing in high-performance liquid chromatography instrumentation, Chrom Tech is a leading distributor of GC and HPLC products, supplies, and equipment.

Certified "to fit" Vials Our new certified vial, cap and septa products eliminate "fit" and septa contamination concerns associated with other brands. By taking these extra manufacturing and testing steps, we can ensure: Caps thread properly onto vials, providing an air-tight seal; Syringe needles are not damaged by irregular vial bottom thickness

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 equilibrium.

Our major products are high performance liquid chromatography & gas chromatography consumables such as Chromatography Autosampler Vials with closures, inserts, crimper and syringe filters,etc; Water analysis consumables such as COD test tube. Zhejiang Aijiren Technology Co.,Ltd was founded in 2010.

SPE Cartridges. Solid phase extraction (SPE) is an increasingly useful sample preparation technique. With SPE, many of the problems associated with liquid-liquid extraction can be prevented, such as incomplete phase separations, less-than-quantitative recoveries, use of expensive, breakable specialty glassware and disposal of large quantities of organic solvents.
