Chemetrics - K-6010D - Iron (Total & Soluble) VACUettes Kit

ITEM #: 12643730
Iron is present in nature in the form of its o x ides, or in combination with silicon or sulfur. The soluble iron content of surface waters rarely e x ceeds 1 mg/L, while ground waters often contain higher concentrations. The National Secondary Drinking Water Standard for iron is 0.3 mg/L, as iron concentrations in e x cess of 0.3 mg/L impart a foul taste and cause staining. High concentrations in surface waters can indicate the presence of industrial effluents or runoff.
Iron contamination in oil field brines are typically a result of corrosion processes of iron-containing metallic components and equipment. Accumulation of insoluble iron salts in a brine completion fluid can result in substantial formation damage and can significantly affect the productivity of an oil well. Quantifying total iron in brine is critical.

With the Phenanthroline Method, ferrous iron reacts with 1, 10-phenanthroline to form an orange-colored chelate. To determine total iron, thioglycolic acid solution is added to reduce ferric iron to the ferrous state. The reagent formulation minimizes interferences from various metals. Results are e x pressed as ppm (mg/L) Fe.
Kit comes in a plastic case and contains everything needed to perform 30 tests (e x cept distilled water): Refill, Low and High Range Comparators, Activator Solution, dilutor snapper cup, small micro test tube, 5 mL micro test tube, and instructions.
Range: 0-30 & 30-300 ppm
MDL: 5 ppm
Method: Phenanthroline (total & soluble)
Note: Kit contains only enough Activator Solution to perform appro x imately 7 total iron tests.
