WHAT CAN WE DO FOR YOU?
Here at the Bio Analysis Centre we have the capability to run samples through our UHPLC (Ultra High Performance Liquid Chromatograph) or LCMS (Liquid Chromatograph Mass Spectrometer). Shimadzu (1), the manufacture of the machinery, ran a Multiple Residue Analysis of 210 Pesticides in Food Samples by Triple Quadrupole UHPLC – MS/MS.
Pesticide residue on food can severely affect human health, so governments and food manufacturers established regulations which set the limits in a range of 0.01 – 10 mg / kg depending on the toxicity of the pesticide. For food used in the production of baby foods, the detectable level of pesticide must be less than 0.01 mg / kg along with prohibiting the use of certain toxic pesticides.
Linearity was investigated over a nine point calibration, with samples ranging from 0.5 μg / kg – 0.2mg / kg or 0.5 – 200 parts per billion (ppb) analysed in duplicate; calibration samples were injected once in increasing order and once in decreasing order. From that the Mass Spectrometer calculated from the area of the peak the concentration by correlating to the calibration curve associated with the specific pesticide.
This exact assay can be conducted here at the Bio Analysis Centre, if you have a similar project or any enquiries for any other assay, please contact us.
