Abstract
An ion chromatography system includes a separation column configured to separate components of a solution; a non-destructive detector; and a concentrator configured to capture components of a check standard after they leave the conductivity non-destructive detector; and release the components of the check standard to the separation column.
Claims25
An ion chromatography system comprising:
- a separation column configured to separate components of a solution;
- a non-destructive detector;
- and
- a concentrator configured to
- capture components of a check standard after they leave the non-destructive detector;
- and
- release the components of the check standard to the separation column.
4 more elements
A method of reusing a check standard comprising:
- separating the components of the check standard using a separation column;
- detecting the components of the check standard using a non-destructive detector to obtain a first chromatographic data set;
- capturing the components of the check standard with a concentrator;
- and
- releasing the check standard from the concentrator to the separation column to repeat the separating, suppressing, and detecting steps to obtain a second chromatographic data set.
2 more elements
A method of monitoring the performance of an ion chromatography system, comprising:
- separating the components of the check standard on a separation column;
- detecting the components of the check standard using a non-destructive detector to obtain a first chromatographic data set;
- capturing the components of the check standard with a concentrator;
- and
- releasing the check standard from the concentrator to the separation column;
- repeating the separating, suppressing, and detecting steps to obtain a second chromatographic data set;
- comparing the first chromatographic data set to the second chromatographic data set to evaluate the performance of the separation column;
- providing a user with a status indicator of the state of the ion chromatography system.
