- Scope
- This standard specifies the inductively coupled plasma emission spectrometry method for the determination of 32 elements in water. This standard applies to silver, aluminum, arsenic, boron, barium, beryllium, bismuth, calcium, cadmium, cobalt, chromium, copper, iron, potassium, lithium, magnesium, manganese, molybdenum, Determination of soluble elements and total elements of 32 elements including sodium, nickel, phosphorus, lead, sulfur, antimony, selenium, silicon, tin, strontium, titanium, vanadium, zinc and zirconium. The method detection limit of each element in this standard is 0.009 mg/L~0.1 mg/L, and the lower determination limit is 0.036 mg/L~0.39 mg/L. Please see Appendix A for the method detection limits of each element.
