GB/T 24800.13-2009 《Determination of nitrite in cosmetics by ion chromatography method》 Related products
The GB/T 24800.13-2009 standard specifies the determination method of nitrite in cosmetics, which is suitable for skin care cosmetics. The standard uses Ion chromatography to detect nitrite, with a detection limit of 0.000025% and a quantification limit of 0.00005%. Sample Handling involves demulsifying with acetonitrile, high-speed oscillation, after centrifugation, diluting and filtrating the sample solution, and then analysis by Ion Chromatography and Conductivity detector Detector. The standard also lists the required reagents, instruments and their use requirements, such as the activation step of RP column or Cis column. This method guarantees accurate detection of nitrite, which helps to ensure the safety of cosmetics.
