2 5007we calibrate HPLC once in 6 months while iam doing calibration i came to know that calibration was failed. then how can i justify that the samples analyzed on the system during this 6 months was wright? how can i forward in to the next step for those batches?

why glutent are detected in the rice cereal baby food product even manufacturer claimed that they are using rice and milk only?we have using ELISA to do the test,and rice supposed not containing any glutent,rite?We already repeat the test so many times and it still detected.just wondering where the glutent came from?

I have compare C2H2-air and C2H2-N2O flame AAS on determination calcium. Both use same range of std to plot calibration curve. (2-6ppm) When i measure the sample with phosphate, KCl and LaCl, C2H2-N2O flame give false positive result, around 0.5ppm. When i measure the sample with phosphste, KCl and EDTA. C2H2-N2O flame also give 0.5ppm false positive. But both above mentioned sample would not give false positive when measured by C2H2-air flame. What is the reason?
