Abstract
Method and apparatus for separately collecting the components of a sample separated by chromatography, which uses a time schedule starting from a specific peak on the chromatogram of a sample to be analyzed and comprising those time bands of a first group in each of which peaks are to be detected and those time bands of a second group in each of which peaks are to be neglected, the time bands of the first and second groups occurring alternately and successively, and only in the time bands of the first group collection of a sample component is conducted while a peak is being detected.
Claims6
A method of collecting components of a sample separated by chromatography, comprising:
- setting a time schedule which starts from a specific peak on a chromatogram of a sample whose components are to be separately collected;
- providing said time schedule with a series of time bands of a first group, in each of which peaks on said chromatogram are to be detected for possible utilization in controlling collecting of said sample components, and a series of time bands of a second group, in each of which peaks on said chromatogram are to be neglected, said time bands of said first and second groups occurring alternately and successively;
- using a units of time setting in selecting a time length of each of said time bands, individually;
- introducing said sample into a chromatograph;
- detecting said specific peak to start said time schedule;
- detecting at least one peak on the chromatogram of said sample in at least one of said time bands of said first group;
- disregarding any peaks on the chromatogram of said sample occurring in said time bands of said second group;
- and
- collecting a component of said sample that is causing said at least one peak.
