Spark-OES analysis for metals & alloys

This metal screening analysis includes the semi-quantitative determination of 70 elements. The method can be used, for example, to determine the background concentrations of metals in environmental samples or to study the elemental distribution of unknown samples. Screening is also often performed to assess which metals should be analyzed by a quantitative method. The measurement is performed using a high-resolution ICP-MS technique (ICP-SFMS), which can identify very low elemental concentrations. A semi-quantitative determination of the following elements is included: Ag, Al, As, Au, B, Ba, Be, Bi, Br, Ca, Cd, Ce, Co, Cr, Cs, Cu, Dy, Er, Eu, Fe, Ga, Gd, Ge, Hf, Hg, Ho, I, Ir, K, La, Lu, Mg, Mn, Mo, Na, Nb, Nd, Ni, Os, P, Pb, Pd, Pr, Pt, Rb, Re, Rh, Ru, S, Sb, Sc, Se, Si, Sm, Sn, Sr, Ta, Tb, Te, Th, Ti, Tl, Tm, U, V, W, Y, Yb, Zn and Zr. However, please note that some elements may not be determinable due to matrix interference. During this semi-quantitative analysis, the instrument is calibrated for about 30 elements. The rest of the analytes are quantified using sensitivity factors for calibrated elements with similar mass and first ionization potential, considering isotope abundances. Quantitative analysis is also available at an additional price. During this analysis, all elements are calibrated (excluding halogens and Os). Please ask for an offer for this service.

Stable isotope analysis of the elements in solid samples with isotope-ratio mass spectrometry (IRMS). Measurable isotopes given below: Isotope ratio Description δ13C Ratio of 13C to 12C δ2H (δD) Ratio of 2H to 1H (deuterium to protium) δ15N Ratio of 15N to 14N δ18O Ratio of 18O to 16O δ34S Ratio of 34S to 32S The results are reported as per mille (‰) deviations of the ratio of the heavy and light isotopes for the given element in comparison to a standard reference material. We have more than 30 IAEA, USGS, and in-house isotopic standards available to accommodate a wide range of expected ratios. Samples should be non-hazardous, dry, thermally decomposable and homogenous. The minimum sample count is 50 per batch. The price and turnaround time displayed apply to conventional sample matrices. The analysis is suitable for a wide range of materials, including, but not limited to, soils, plants, and insect tissue. All of our stable isotope analyses are conducted by ISO 17025-accredited facilities.

XRF is a quantitative and qualitative method that can be used to analyze solid and liquid materials. This method is intended for a standard screening of homogeneous materials that do not require special sample preparation, precautions, or have any other special requirements. Wavelength-dispersive XRF (WDXRF) is used to perform the measurements unless energy-dispersive XRF (EDXRF) is specifically requested.

We have various testing services available for ultrapure water. Pricing depends on the selected parameters 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.

Reporting limits depend on the element and specific 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 is typically 1 ng/L. The sample must be delivered in a plastic PFAS-free bottle, preferably made from HDPE.

Rutherford Backscattering Spectrometry (RBS) can be used to measure the composition of solid samples quantitatively at the surface as well as depth profiling. RBS is used for the analysis of heavy elements and can be combined with ToF-ERDA when lighter elements also need to be analyzed. Elements with similar mass can be difficult to differentiate.

Simultaneous determination of the following elements in water samples with the ICP-MS technique (AFS is used for Hg): Element LOQ (µg/L) Ag 1 Al 5 As 1 B 10 Ba 0.5 Be 0.2 Ca 50 Cd 0.02 Co 0.5 Cr 0.2 Cu 1 Fe 2 Hg 0.005 K 50 Li 1 Mg 3 Mn 0.5 Mo 1 Na 30 Ni 2 P 50 Pb 0.5 Se 1 Sn 1 Ti 1 Tl 0.5 U 0.1 V 1 Zn 2 The sample is homogenized and acidified (HNO3), after which the analysis is performed from the liquid phase. The displayed price applies to natural waters (for example, river or lake water). If the sample contains a lot of solids or the matrix is otherwise significantly different from natural water (for example, wastewater and industrial water), different analysis methods need to be used, which will affect the price and the quantification limits. The concentration of each element is reported in µg/l.

Determination of the total organic fluorine (TOF) content in combustible materials using combustion ion chromatography (CIC). By default, TOF is analyzed as total fluorine (TF). If required, total inorganic fluorine (TIF) can be measured as well, and TOF calculated as the difference between TF and TIF. TOF analysis gives information about the total amount of organic fluorinated compounds. It can also be used to evaluate the presence of per- and polyfluoroalkyl substances (PFAS) in the material, even though individual PFAS compounds can't be analyzed with this method. The analysis is suitable for many different materials. Please describe the sample in detail when requesting an offer to help us prepare a quote quickly.
