2014/1/1 · Blank solution—Pipet 6 ml of water into a vial fitted with a septum and a crimp cap, and seal the vial. Heat the sealed vial at 80 °C for 60 min. Chromatographic system (see Chromatography , in the general procedure 〈621〉)—The gas chromatograph is equipped with a flame-ionization detector and a 0.53-mm × 30-m fused-silica capillary column coated with a 3-μm film of stationary phase G43.
Pierce the vial septa, then screw the needle into the vial by rotating the needle depth gauge. Maintain the injection port temperature below the maximum recommended temperature of the fiber. Conduct headspace sampling whenever possible to minimize extraction or carry over of high molecular weight compounds that coat the fiber.
The Crimp Top headspace vials are made of borosilicate hydrochloric acid. It has a transparent and amber color and can withstand a temperature range of -60 to 200 degrees Celsius. Generally speaking, the volume of the headspace vial is 10-20ml, and the
2005/11/1 · Immediately upon thawing, 10 mL of the tomato homogenate was dispensed into a 20 mL glass vial, which was sealed using crimp-top caps with TFE/silicone septa seals (Alltech Associates Inc., Deerfield, IL, USA).

Crimp top vials are available with 3 differnt rim heights: 3mm, DIN crimp top with 3.6mm and 4mm. When using only one crimper, tedious adjustments for the different heights are necessary. The standardized DIN crimp top avoids this problem.
A gas chromatographic procedure with headspace analysis and flame-ionization detection is described for the determination of the chlorofluorocarbon substitute 1,1,1,2-tetrafluoroethane (HFA-134a). A 0.5-2 mL sample of heparinized whole blood from a laboratory animal or human is added directly into a presealed headspace vial from which an equivalent volume of air has been removed.

1991/4/1 · To prepare a sample for analysis, 2 ml of water containing 2 mg of sodium azide were placed in a 10-ml crimp-top vial (23 mm o.d., 47 mm in height; Alltech Associates, Deerfield, IL) and frozen. When the ice in the vial began to thaw slightly, 1 ml of blood was pipetted onto the ice with an Eppendorf Combitips pipettor (Brinkman Instruments, Westbury, NY) and an 18-gauge needle.
