The Aijiren Automatic Liquid Sampler (ALS) provides reliable, fast, and precise injections for Aijiren GC and GC/MS systems. The modular design allows this autosampler to grow with your lab. Start with a tower and 16 vials. Expand to the 150 vial tray.

2 The sampler pressurizes the vial with gas. See Figure 3. 3 After equilibration at pressure, the pressurized vial gases vent through the sample loop, filling the loop with sample. Note that the vial vents to atmospheric pressure in this case, not to a high column

Goal This work illustrates the headspace GC-MS method development and optimization for volatile extractable and leachable (E&L) compounds. In particular, the focus has been on the partition coefficient of common organic volatile impurities (OVIs) in a variety of

Aijiren GC sample introduction systems increase the efficiency, performance, and flexibility of your gas chromatography systems. In addition to offering reliable and consistent injections from less than 1 µL to large volumes, GC autosamplers provide the ability to perform automated sample preparation procedures that range from simple dilutions to complicated derivatizations.

I write to you my actual standard preparation. I weight X g of MeOH, X g of Isopropanol and X g of DMF in a 25 ml volumetric flask ( All three solvent are weight in the same flask). I fill up to volume with DMSO. After I dispense 10 ul of this solution in n vials with

IntroductionStatic headspace extraction (SHE) is one of the most important sample preparation techniques for gas chromatography. Ease of sample preparation, automation and instrument sensitivity make static headspace extraction the technique of choice for the analysis of volatile compounds in a wide range of concentrations and sample types, from part-per million and lower to percentages

The first part of this chapter presents the main objectives for performing. derivatization of a sample to be analyzed by gas chromatography (GC) or gas. chromatography/mass spectrometry (GC/MS

Several headspace systems are available; transfer to the gas chromatograph is with a gas sampling valve, a gas-tight syringe, or the pressure-balanced system that is unique to Perkin–Elmer [14]. Recently, commercial headspace samplers have become available with the capability of trapping the gas sample onto a sorbent instead of introducing it directly into the gas chromatograph.

1987/1/1 · Preparation of samples A sample of 50-300 mg was directly weighed in a HS6 vial and 1.0 ml diethylene Gas Chromatography Head Space Analysis, Wiley. New York, 1985. 5 B. Kolb, Applied Head Space Gas Chromatography, Wiley, New York, 1984

Afterwards, aliquots of 3 g of blanched carrots were placed in 20 ml gas-tight vials and hermetically sealed with a gas-tight septum. A total of 24 vials were prepared for each temperature tested (−18 °C, 4 °C, 25 °C, 40 °C), in order to have three replicates (three different vials) for each day of measurement (1, 4, 8, 12, 19, 26 days).
