Integrated Wastewater Discharge StandardThe rapid development of industry brings benefits but also problems. The concentration of total phosphorus in industrial wastewater cannot be ignored.Phosphorus is mostly inorganic compound phosphorus, which is mainly composed of orthophosphate and fused ring

scientific research departments for soil, blood, urine, nails, food, dairy productsPFA and PTFE digestion tubes are laboratory supplies used for digestion of organic and inorganic samples in the chemical, pharmaceutical, and environmental industries. PFA stands for perfluoroalkoxy, while PTFE stands

Thermo Fisher 1ml/Eppendorf 5ml/Sartorius 0.1ml replacement tips.PFA microtipsⅠ. Product introductionPFA is also called Perfluoroalkoxy alkanes or Teflon, which can be used in trace analysis, isotope detection, ICP-MS/OES/AAS analysis and other experiments. PFA pipette tip, specifications: 0.1ml, 0.

Most high explosives contain carbon, hydrogen, nitrogen and oxygen atomsA series of recent experimental results have overturned my long-standing thinking: “Using different isotopes and different modes to get the same results, it can be considered that elements have no mass spectrum interference.”Alt

Excellent corrosion resistance: PFA material can withstand various strong acids, strong alkalis, hydrofluoric acid and organic solventsInductively coupled plasma mass spectrometry (ICP-MS) is one of the most important spectroscopic techniques. It is a multi-element technique with extremely high sens
