Water Analyses contain elements, B, Si, S, and P

Water analysis data obtained from ICP measurements will contain concentrations for non metals like B, P, S, and Si. These elements do not exist in the water, rather they exist as dissolved ions. if you see these elements in the analysis, then you need to convert them to the following

Table 1 Converting element concentration to species for Brine or Water Analysis

ICP data	Aqueous Species	Formula to enter	Formula weight multiplier
B, boron	boric acid	H3BO3	B (mg/l) * 5.71 = H3BO3 (mg/l)
Si, Silicon	silica	SiO2	Si (mg/l) * 2.14 = SiO2 (mg/l)
P, Phosphorus.....	dihydrogen phosphate.....	H2PO4-1	P (mg/l) * 3.13 = H2PO4 (mg/l)
S, Sulfur	sulfate or sulfide	HS-1 or SO4-2 (cannot tell from total S only)....	S (mg/l) * 1.03 for HS-1 (mg/l) or
			S (mg/l) * 3.0 for SO4-2 (mg/l)
