GC columns can generally be split into two categories: packed columns and capillary columns. Depending on your application, this will influence the type of GC column you need and the specifications of the column in that category.

Choosing the correct liner is crucial because it facilitates the transfer of the sample to the GC column. It can significantly influence the accuracy of the analysis.

Matrix spiking is a technique used in analytical chemistry to evaluate the performance of an analytical method for a specific sample type (matrix).

Pesticide residues can also be found in food and crops, raising significant concerns. To ensure this is monitored correctly samples must be collected and analyzed to ensure the crops and food products meet safety standards.

GC-MS method development ensures that analytical assays are accurate, precise, and reliable. This begins with a thorough understanding of the sample.

Water testing is bound by stringent regulatory standards that can vary depending on geographical location. The detection of water impurities within drinking water, groundwater, and wastewater is essential to maintaining public health and environmental standards.

The major difference between a standard phase GC and a MS phase GC column, such as a SCION-1 vs a SCION-1MS, is column bleed. The column bleed causes an increase in baseline signal which is an issue when aiming to identify analytes with low signal to noise ratio.

SCION Instruments' pre-configured GC-based RGA Analyzer offer several advantages over competing systems from manufacturers like Agilent Technologies, Thermo Fisher Scientific, or Shimadzu.
