WebOwing to its potential to form HCl which can cause damage to the inlet and column, chromatographers should be careful when using DCM as a solvent in conjunction with Hydrogen as carrier gas. This experiment shows that it is possible to use Hydrogen as carrier gas for standards and extracts that are required to be in DCM. WebJun 28, 2015 · Performance Improvement Coach. HCL Technologies.

WebIf the sample is homogenised in an organic solvent, the analytes are extracted with HCl. In most cases, further purification is achieved by consecutive acid-base partition processes or by combining this technique with extraction using sorbents.
