SupelMIP™ Clenbuterol

- A specific SPE sorbent optimised for extraction
of clenbuterol from biological samples.

Features and applications

Clenbuterol is extracted with a high recovery. Due to the selectivity this extraction method enables determination at a limit of quantification of 0.5 ng/ml using the economically favourable detection system: HPLC-UV.

The chromatograms show the extraction clean-up of a typical analyte from a 5 ml urine sample. Superior clean-up with the MIP sorbent is shown in red, whereas the other chromatograms show clean-up with a much higher level of chemical noise, using mixed-phase SPE sorbents.

Recovery, precision and accuracy are given together with chromatograms and SPE procedure in the Data Sheet. For further reading we also refer to the literature list below.
