Abstract
A method and system for solid phase extraction of a compound of interest from a sample matrix using a syringe having a barrel and a plunger, a sorbent for use with the syringe, and a desalting purification column having an end configured to receive liquid from the syringe body.
Claims20
A method for extracting a compound of interest from a sample matrix, comprising the steps of:
- a. drawing a sample matrix into a syringe having a plunger;
- b. contacting the sample matrix with a sorbent to bind the compound of interest to the sorbent;
- c. drawing an elution buffer into the syringe containing the sorbent;
- and
- d. expressing the elution buffer containing the compound of interest through a desalting column subsequent to pushing the elution buffer containing the compound of interest through the sorbent.
