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. With conventional headspace, the analytes are normally present at concentrations ranging from parts per billion to low percentage levels; with trapping, samples with much lower levels of analytes can be accurately analyzed.
Headspace (HS) coupled with gas chromatography (GC) provides quantitative and qualitative information about the volatile components that are present in complex sample matrices. The Aijiren Headspace Sampler is part of Aijiren’s line of gas chromatography products.
Headspace vials are available in clear or amber glass with a round or flat base, a crimp seal with a beveled or square edge finish, or with a screw-thread finish. Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs.
Hence, a reproducible Gas Chromatography with static headspace method was developed for the quantitative determination of 12 Residual solvents in Dapagliflozin Amorphous. This method was successfully validated according to the International Conference Harmonization (ICH) guidelines

Headspace gas chromatography requires headspace vials and caps because they can withstand the pressure from the gas. Chrom Tech has a wide selection of high-quality crimp and screw thread headspace vials available in clear or amber glass with associated 18-and 20-mm headspace closures. Our headspace vials can be ordered as either flat or round
