Method and system for injecting an internal standard into a portable gas analyzer system and an associated reusable sample cartridge

A reusable sample cartridge comprising:

• a cartridge housing;
• a collecting element positioned at least partially inside the housing;
• and
• a docking interface structured to interact with a sample analyzer,
• wherein,
• the collecting element is structured to adsorb a gas sample and a measured amount of an internal standard gas, and
• the gas sample and the measured amount of internal standard gas are desorbed from the collecting element at the same during an analysis process.

A system for analyzing a gas sample, comprising:

• a sample collector structured to obtain a gas sample from an environment;
• and
• a sample analyzer structured to removably couple with the sample collector, wherein the sample analyzer is configured to,
• measure an amount of internal standard and adsorb the measured amount of internal standard onto the sample collector,
• desorb the gas sample and the measured amount of internal standard from the sample collector at the same time,
• analyze the gas sample and the measured amount of internal standard,
• perform a quantitative analysis of the gas sample based on the analysis of the desorbed measured amount of internal standard, and
• determine a type of the gas sample and an amount of the gas sample.
