In R&D and production, it is often necessary to analyze the content of various elements in samples, and AA, ICP-OES, ICP-MS is usually used to analyze the elements of samples dissolved in ultra-pure reagents:
1. Analyze the metal elements in the sample by signal absorption spectroscopy, suitable for G1/G2 grade products.
2. Spectral analysis of metal elements in plasma samples, applicable to G3/G4 grade products – ppb grade.
3. Analyze the metal elements in plasma samples by mass spectrometry, and apply G5/G6 grade products – ppt grade.
Wrap:
Imported high-purity, corrosion-resistant fluoropolymeric resin PFA material is used as the packaging container for G4, G5 and G6 series products;
Use high-density polyethylene bottle (HDPE) as the packaging material of G1~G3 series products;
The 500mL packaging products are secondary packaged in PE bags, and the outer layer of PET bottles is protected to improve the safety of the products during transportation.
Other ultra-pure reagents can be customized, and detailed needs can be contacted by our salesman to communicate specifications
