Headspace vials often come in larger volumes than the 2-mL vials used in many liquid sampling systems. Common offerings are 10-mL, 20-mL and 22-mL capacities. Larger vials accommodate larger sample volume and/or a larger headspace above that sample.
Oct 13, 2005 · We have a headspace analyser that can only use 10 mL or 20 mL vials. However, a customer has supplied a method where 22 mL vials are to be used. Would this 2 mL difference in volume be significant? The sample volume is approx' 2 mL.
a 20-mL headspace vial. Ethylbenzene (EB), cumene, and styrene monomers (SM) are discussed here. Therefore, 2 µL DMF solution containing 10% v/v EB, cumene, and SM was transferred in a 20-mL headspace vial as an external standard. Configuration All experiments were performed using a Headspace Sampler (HSS) with a A GC. The A GC was

Apr 8, 2018 · Sample is 100mg of SSG in 20mL headspace vial. Add 5.0mL of DMSO. Please note that this has happened about a week ago. I thought I clogged the headspace autosampler and I cranked the oven, loop, and transfer line up to 150, 160, 170 each to try to get whatever out. It was giving me nice peaks but then all of a sudden no more peaks. Thanks Jeff
These vials have a thicker glass wall to withstand higher temperature and internal pressure for the analysis of volatile gas in the vial’s headspace. Headspace vials with 20 mm crimp tops and 18 mm screw tops in sizes ranging from 6 mL to 20 mL are available in clear or amber glass.
Headspace Vials PerkinElmer offers a variety of GC headspace vials, caps and septa to fulfil your application needs. Our patented vial and cap design incorporates pressure-relief features which guarantee safe operation with the high pressure typically developed during thermostatting. Ordinary vials and caps without these safety features may burst.

2.27.4.3.3 Dynamic Headspace – Full Vaporization Technique. A modified DHS technique developed by Markelov 31 is the full vaporization technique (DHS-FVT). This approach uses a small volume of liquid sample (5–50 μl) placed into a standard headspace vial and heated to completely vaporize the sample.
