Product research and development are one of our premises at Premifab. The reasons for establishing our own analytical chemical laboratory – Laboratory for Organic Solvents – include the vision of a product tailored to the customer and his desired use, as well as the assessment of the quality of the input and recovered materials.
The first phase of solvent assessment involves classifying recovered solvents as acceptable or unacceptable for recovery. The classification depends on the composition, the amount of undesirable components, and how dangerous the treatment process is. After a detailed composition analysis of the samples obtained, the second stage of the assessment will determine the quality of the recovery process, which includes the efficiency of the treatment and the very possibility of using the recovered solvents. This phase includes both large scale recovery and continuous analysis of the composition as needed.
- Gas chromatograph (GC) for determining the content of an individual organic solvent;
- Karl Fischer coulometric titrator (KFT) for determining water content;
- Determination of the pH values;
- Measurement of specific electrical conductivity;
- Density determination.
All standard procedures in the laboratory are done according to the GLP (good laboratory practice).
The accreditation area according to ISO/IEC 17025: 2017 refers to testing of organic-based waste samples, regenerates and chemicals, and we have accredited two in-house methods – water determination by Karl Fischer coulometric titration and composition testing by gas chromatography (GC-FID).
