Laboratory testing services

Phase identification and quantification (Rietveld analysis) of a crystalline powder material using X-ray diffraction (XRD). The analysis can also provide unit cell dimensions. The analysis is only suitable for materials with at least one crystalline phase. The quantification accuracy is roughly 0.1 %, depending on the sample matrix and the phase in question. The available temperature range for XRD measurements is 25-1100 °C and the crystallinity can be studied as a function of temperatures. The measurements can be done under a normal atmosphere, inert gas, or vacuum. Please contact our experts to discuss the available temperature and atmosphere combinations. Please mention which crystalline phases your material contains and which ones are you interested in quantifying when requesting testing. However, the method can be applied to unknown phases as well. Either a tabletop or a synchrotron XRD can be used to perform the measurements.

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.

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 and 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.

This analysis is used to assess the ultimate aerobic biodegradability of materials in controlled composting conditions by the ISO 14855 standard. Testing is most typically performed on biodegradable plastics and packaging materials. Aerobic biodegradation is the process where organic materials are converted into carbon dioxide (CO2) in environments suitable for composting. The testing conditions can be tailored to simulate either industrial or domestic compost settings. It's important to note that this test specifically measures aerobic biodegradation. It does not cover chemical analyses, material disintegration, or ecotoxicity evaluations necessary for a comprehensive compostability assessment by EN 13432 and ASTM D6400 standards. However, the test is an excellent tool for comparing different product variations in the early stages of development, before conducting a full compostability assessment. The cost of the test varies based on the chosen conditions and the product, with durations ranging from 45 days to 12 months.

Pyrolysis gas chromatography-mass spectrometry (py-GC-MS) analysis to determine the identity of an unknown polymer sample. During the measurement, the sample is instantaneously heated in an inert atmosphere or vacuum. This causes the sample to decompose into smaller molecular fragments which are then analyzed with GC-MS. Different types of polymers can be identified by their unique decomposition products. This includes, but is not limited to: PE, PP, PS, ABS, PMMA, PET, PC, PVC, polyamides, natural & synthetic rubbers, and more. The price includes the basic preparation and analysis of the sample. More extensive sample preparation is subject to additional costs.

The formulated package aims to provide sufficient information to identify the sample components and their quantities. Most typically, the following methods are used to analyze unknown substances: CHNOS elemental analysis and TGA: These methods will provide information on the sample composition, mainly if the sample is organic or inorganic and if it has one or more constituents. XRD, XRF, ICP, and IC: These methods will be used to provide more detailed qualitative and quantitative information on the inorganic constituents of the sample. 1H & 13C NMR, and GC/HPLC-MS: These methods are used to identify and quantify organic constituents. Our whole analysis catalog can be used to analyze the sample if required. Please contact our experts to start building the unknown sample analysis package designed specifically for your needs. Please also note that the stated required sample amount is the preferred amount. Analysis of smaller sample quantities can also be conducted.
