X-Ray Reflectometry (XRR) analysis is used to measure the density (g/cm3), thickness (nm), and roughness (nm) of thin films. The method is applicable to the characterization of single- or multilayered thin films, as it provides information on the thickness and density of individual layers of the sample material as well as the roughness of the interphases. Greatest accuracy for XRR thickness measurements is generally achieved for samples containing 1-150 nm thick surface layers with under 5 nm RMS roughness. Thicker films and coatings with rougher surfaces can also be characterized, but the accuracy of thickness determination decreases as the thickness and roughness of the film or film stack increase. >150 mm wafers are typically cut to fit the sample holder. Please let us know if you need testing for larger wafers that cannot be cut into pieces. The available temperature range for XRR measurements is 25-1100 °C, and crystallinity can be studied as a function of temperature. The measurements can be performed under a normal atmosphere, inert gas, or vacuum. Measurements are typically performed using one of the following instruments: Rigaku SmartLab, Panalytical X'Pert Pro MRD, Bruker D8 Discover. Please let us know if you have a preference for a specific instrument.

Asymmetric flow field flow fractionation (AF4) of polymers using a multi-angle light scattering (MALS) detector. This analysis is suitable for polymers of ultra-high molecular weight (UHMW) >1E6 g/mol. This includes polymers such as polyisoprene (synthetic and natural rubber), polybutadiene, styrene-butadiene rubbers, polyisobutylene, or acrylic and methacrylic emulsion copolymers. AF4-MALS also provides superior separation of branched polymers. The technique will measure the molecular weight distribution of polymer samples in a graphical format, the dispersity, Đ, and determine the actual molecular weight averages, Mn, Mw, and Mz. The samples must be soluble or able to be measured from a solution at room temperature. The type of polymer and the necessary solvent will affect the cost.

Gel permeation chromatography (GPC), a.k.a. size exclusion chromatography (SEC), of polymers using a multi-angle light scattering (MALS) detector. This technique will measure the molecular weight distribution of polymer samples in a graphical format, the dispersity, Đ, and determine the actual molecular weight averages, Mn, Mw, Mz. In contrast to other techniques using RI detectors and calibration standards, the MALS method will determine the true molecular weight of the sample. The samples must be soluble or able to be measured from a solution at room temperature. The type of polymer and the necessary solvent will affect the cost of the analysis.

Gel permeation chromatography (GPC), a.k.a. size exclusion chromatography (SEC), of polymers using either a refractive index (RI) detector or a multi-angle light scattering (MALS) detector. This product is suitable for polypropylene or polyolefin polymers that are only soluble at high temperatures in 1,2,4-Trichlorobenzene (TCB). This technique will measure the molecular weight distribution of polypropylene (PP) samples in a graphical format, the dispersity, Đ, and determine the molecular weight averages, Mn, Mw, and Mz. Opting for the method with RI detectors will determine the molecular weight relative to a calibration standard. Please note that the numerical values determined for molecular weight by the RI method are not absolute. Opting for the MALS method will determine the true molecular weight of the sample. The choice of detector for the analysis will affect the cost. Please contact our experts for a quote tailored to your needs.

Determination of the nitrogen or helium transmission rate of plastic films and sheet-like materials with the differential pressure method. Testing is performed on three parallel samples. Measurement conditions (temperature and relative humidity) can be chosen according to the intended use of the material. Please disclose the desired temperature (from 5 °C to 95 °C) and relative humidity (either 0% or from 10% to 90%) upon ordering. Oxygen (O2) and carbon dioxide (CO2) transmission rates can also be determined with the manometric method upon request, but the following, more cost-efficient measurements are used more often: OTR of films and sheeting, CO2 transmission rate of films and sheeting.

The peroxide value (PV) measures hydroperoxides formed as a result of the autoxidation of unsaturated fatty acids in food and feed products. Accumulation of autoxidation products affects sensory quality and is potentially harmful to human and animal health, making PV an important quality indicator in the food industry. Autoxidation reactions occur at different rates during the manufacturing, storage, and use of food and feed, but are generally sped up with elevated temperatures and exposure to light. This method includes an extraction step, after which the determination of peroxide value is performed on the extracted fat or oil. The method is suitable for all food and feed products that contain fat.

Recyclability testing of paper and cardboard packaging according to the Aticelca 501:2023 method. The method is based on the Italian UNI 11743: 2019 standard. The following properties are evaluated: Disintegration behavior and recyclable content, Impurity content (e.g., plastic, coatings, adhesives), Visual appearance. Based on the results, the material is given a recyclability classification of A+, A, B, or C. A+ indicates a highly recyclable material, while C indicates a product with poor recyclability. The material can also be classified as non-recyclable with paper.

The TOTOX value gives an indication of overall oxidation in fats and oils. It is calculated using indicative values for primary oxidation products (peroxide value) and secondary oxidation products (p-Anisidine value). For TOTOX value determination, peroxide and p-Anisidine analyses are performed and their results are reported along with the total oxidation value. Testing is suitable for animal and vegetable fats and oils, fatty acids, and their mixtures. Milk fats and lecithin cannot be analyzed.
