Mycotoxin standards solutions are used routinely in mycotoxin analysis. They can be used to prepare a calibration curve for the HPLC system, ensuring accurate determination of the. Calibration gives us confidence that when the detector reports a mass (or more properly mass-to-charge ratio, m/z) for a compound, we can be sure that the reported value is correct. This means that we need to use a well-defined standard for the procedure. Tuning is a much more common process than calibration. The essence of tuning is that we want the instrument to give the maximum signal.

High-performance liquid chromatography (HPLC), formerly referred to as high-pressure liquid chromatography, is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material The combined relative standard deviation (%RSD) for intra-day and inter-day precision for all eight analytes varied from 2.5% to 5.2% and 0.28% to 5.5%, respectively. The %RSD for the repeatability study varied from 1.1% to 5.5%. The recoveries from spiked cannabis matrix samples were greater than 90% for all analytes, except delta-8-tetrahydrocannabinol ( Analytical high-performance liquid chromatography (HPLC) systems can be turned into purification systems by adding a fraction collector to the stack. The analytical column can be used for purification as well, as long as the method is properly optimized with respect to selectivity and sample load. This technical overview presents the purification of a small molecule using an Agilent 1260.
