Heavy metal (Pb, Cd, As, Hg) analysis package

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.

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.

The measurement determines the content of dissolved silicon in ultrapure water using UV-Vis spectroscopy (molybdenum heteropolyblue method). The typical detection limit is 0.7 ppb (this only applies to ultrapure water, as samples with higher impurity levels must be diluted to avoid equipment saturation, which raises the LOQ). Samples must be collected in suitable sample containers designed for ultrapure water. Measurlabs can provide the required sample vessels upon request.

Determination of 36 elements in ultra-pure water with the ICP-MS technique. The measurement includes the following elements: Al, Sb, As, Ba, Be, Bi, B, Cd, Ca, Cr, Co, Cu, Ga, Ge, Au, Fe, Pb, Li, Mg, Mn, Mo, Ni, Nb, Pt, K, Ag, Na, Sr, Ta, Tl, Sn, Ti, W, V, Zn, and Zr. The expected LOQ varies from 0.001 to 0.009 ppb, depending on the element and the exact sample matrix. Samples must be collected in suitable containers designed for ultrapure water. Measurlabs can provide the required sample vessels.

Determination of elements in food, feed, and dietary supplements with ICP methods (ICP-MS, ICP-AAS, ICP-OES). Elements can contribute to the quality and properties of food and feed in several ways. Some are essential minerals that enhance nutritional value, while others (e.g., heavy metals) are considered undesirable contaminants with maximum levels set in EU food contaminant legislation. Some elements can also contribute to the sensory properties of products. Regulation (EU) No 1169/2011 allows the declaration of certain minerals if the food contains them in significant amounts in relation to daily reference intakes. The EU also keeps a database of authorized mineral additives in feed and regulates the allowed tolerances between declared amounts and analyzed amounts. Elements that are generally considered hazardous contaminants are regulated by Regulation (EU) No 2023/915 and Directive 2002/32/EC. The most common elements that are available for analysis include: Aluminium (Al), Arsenic (As), Boron (B), Cadmium (Cd), Cobalt (Co), Chromium (Cr), Iron (Fe), Manganese (Mn), Mercury (Hg), Nickel (Ni), Lead (Pb), Selenium (Se), Tin (Sn), Zinc (Zn), Molybdenum (Mb), Calcium (Ca), Phosphorus (P), Magnesium (Mg), Potassium (K), Sodium (Na), Titanium (Ti), Sulfur (S). It may be possible to analyze other minerals or heavy metals upon request. You can get more information on the analysis options and a quote for quantifying selected elements by contacting us.

Spark-OES is a commonly used method to determine the elemental composition of metals and alloys. The method provides a better alternative to other similar analysis techniques (ICP-OES, ICP-MS, XRF) due to its speed and low detection limits. All metallic elements and some non-metallic elements, such as C, N, and S, can be detected in the ppm range. The method is suitable for solid metal pieces with a minimum size of 1 x 1 cm. Sample preparation is included in the analysis.

According to Regulation (EU) No 432/2012, melatonin supplements may be marketed with the following health claims: "Melatonin contributes to the alleviation of subjective feelings of jet lag." The claim can be used if the product contains at least 0.5 mg of melatonin per portion., "Melatonin contributes to the reduction of time taken to fall asleep." The claim can be used if the product contains at least 1 mg of melatonin per portion..
