Ultrapure water testing

We have various testing services available for ultrapure water. Pricing depends on the selected analyses and the number of samples. Please contact Measurlabs to get an offer. Note that we will provide suitable shipping containers based on the analyses that are ordered.

Trace elements by ICP-MS

For the determination of elemental impurities, we offer a basic 36-element and an extended 67-element package.

The basic package includes the following 36 elements: Li, Be, B, Na, Mg, Al, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Sr, Zr, Nb, Mo, Ag, Cd, Sn, Sb, Ba, Ta, W, Pt, Au, Tl, Pb, and Bi.

The extended analysis includes the following elements in addition to the basic package: Ce, Cs, Dy, Er, Eu, Gd, Hf, Ho, In, Ir, La, Lu, Hg, Nd, Os, Pd, Pr, Re, Rh, Rb, Ru, Sm, Sc, Se, Te, Tb, Th, Tm, U, Yb, and Y.

Reporting limits depend on the element and sample matrix, but typically vary between 0.001 ppb and 0.6 ppb. For this analysis, samples must be delivered in Teflon containers.

Hardness

Hardness value can be calculated based on the ICP-MS results.

Silicon and silica (Si, SiO2)

Our service catalog includes the determination of total, dissolved, and colloidal silica (SiO₂). Total silicon is analyzed using the ICP-OES technique, and dissolved silicon by UV-VIS (molybdenum heteropoly blue method). Colloidal silica is calculated as the difference between total silica and dissolved silica.

Total organic and inorganic carbon (TOC and TIC)

We offer TOC determination for ultrapure water samples with a 5 ppb quantification limit. For this analysis, samples must be delivered in certified 40 ml TOC vials. Total inorganic carbon (TIC) analysis can also be performed using a TOC analyzer.

Anions by ion chromatography (IC)

For anions, we have a basic package and a separate package for organic anions.

The basic package includes the following anions: bromide(Br⁻), chloride (Cl⁻), fluoride (F⁻), nitrate (NO₃⁻), nitrite (NO₂⁻), phosphate (PO₄³⁻), and sulfate (SO₄²⁻).

Analysis of organic anions includes: acetate, formate, glycolate, propionate, and butyrate.

Reporting limits depend on the anion and sample matrix, but typically vary between 0.02 and 1 ppb for basic anions and are around 25 ppb for organic anions. For this analysis, samples must be delivered in HDPE bottles.

Cations by ion chromatography (IC)

The analysis package for cations includes the determination of the following cations: ammonium (NH₄⁺), calcium (Ca²⁺), lithium (Li⁺), magnesium (Mg²⁺), potassium (K⁺), and sodium (Na⁺).

Reporting limits typically vary between 2 ppb and 5 ppb. Samples must be delivered in HDPE bottles.

PFAS compounds (24 compounds)

Analysis includes PFOS, PFOA, PFNA, PFHxS, and 20 other selected PFAS compounds. The complete list of compounds can be provided upon request. The reporting limit of the results is typically 1 ng/L. The sample must be delivered in a plastic PFAS-free bottle, preferably made from HDPE.
