Aijiren headspace vials come in two basic sizes (10 mL headspace vials and 20 mL headspace vials). Both flat bottom and round bottom styles are available for use in a wide variety of headspace instrument platforms. Aijiren's headspace vial caps are engineered to prevent sample contamination while providing consistent, secure seals.
Headspace sampling is a type of sample introduction technique for gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). For headspace techniques, the gas layer, or the headspace above the sample in a vial, is analyzed as opposed to withdrawing a volume from within the sample layer (Figure 1).
These are vials are suitable for use when sample volume is limited or when you need to get maximum recovery from the vial. These vials allow small volumes to be sampled accurately by autosamplers with a recoverable volume of much less than 100 µL. High recovery, total recovery and vials with fixed inserts are all classed as microvials.
All of our headspace vials have a greater wall thickness and round base which enables them to withstand pressure up to 60 psig. Low-volume sampling can be achieved by using a 6 mL vial and vial adapter. All PerkinElmer headspace vials are manufactured to specific tolerances that are guaranteed for fit and performance.
Headspace is used to analyze volatile compounds in liquid and solid samples that cannot be injected directly into a gas chromatograph (GC). Examples would be creams and lotions, blood, soil, electronic components, and polymers. Headspace sampling can accommodate virtually any matrix. How does headspace sampling work?

Aug 2, 2022 · A headspace sampling system automates this process by first heating the sample for a measured period of time, and then extracting a small volume of the headspace vapor from the vial and transferring it to the GC column. Figure 3 shows a chromatogram produced from a headspace sample taken from the same sample of perfume that produced Figure 1.
A mid-capacity automated headspace sampler that accommodates standard PerkinElmer 9mL or 22mL sample vials. Up to 40 vials can be loaded into the removable vial magazine for automated analysis. Overlapping thermostatting of up to 12 vials in Constant Mode for maximum productivity. An algorithm adjusts the virtual oven size for maximum throughput.
The term “vial” is somewhat undefined and is usually described as a small, cylindrical, and flat-bottomed container used to hold liquids. Most sample vials are made of plastic or glass, and include a separate or attached lid or closure. Sample vials are categorized by material and also by their size or specific purpose.
The 7697A Headspace Sampler 12-vial capacity configuration is perfect for academic labs and those with small sample loads Standard 111 sample configuration with three priority samples Trays can be exchanged during a sequence for increased sample capacity Hydrogen carrier and auto sleep/wake modes conserve valuable laboratory resources

Figure 1. Headspace pneumatic diagram showing detail of vial pressurization and loop fill EPC. Results The 7697A uses the well established valve and loop system for headspace sample introduction. This system for filling the sample loop has been enhanced by using both forward and backpressure EPC to control precisely the pressures in the
