Bypass injector

  "id": "MLC-T-CHM-001552",
  "term": "Bypass injector",
  "field": "Chemistry",
  "definition": "A component in chromatography that allows a sample to be introduced into the mobile phase stream without interrupting the continuous flow of the carrier gas or eluent through the column. The sample is loaded into a loop, and then a valve switches the flow path to direct the mobile phase through the loop, sweeping the sample onto the column. This design minimizes pressure fluctuations and maintains stable flow conditions.",
