Automated sample purification
DSP-Systems is the official European and North American distributor for Miura – Institute of Environmental Science. Miura is one of the world’s leading Japanese manufacturers of automated sample preparation systems with ‘next generation technology’.
Miura’s highly efficient and ‘green’ systems known as GO-eHT and GO-xHT purify samples for the analysis of persistant organic pollutants, such as Dioxins, PCBs, PBDEs and PCNs. They handle a wide variety of sample matrices such as food & feed, but also environmental samples such as soil, sewage, sludge, water and air. GO-eHT and GO-xHT technology is currently available in Europe and North America.
Sample purification has been made faster and easier than ever before. Organic solvent consumption and exposure is dramatically reduced to less than 100ml per sample without the use of dichloromethane. During sample purification, samples do not have contact with the system therefore risk of cross contamination is eliminated. There are numerous significant advantages that GO-exHT systems offer while boosting laboratory efficiency.
Automated solid phase extraction
DSP-Systems is the official European distributor for PromoChrom Technologies Ltd. PromoChrom is a Canadian company founded in 2007 with specialization in liquid handling solutions. PromoChrom has introduced a wide range of automated sample preparation systems and filed numerous technological patents. Their automated Solid Phase Extraction (SPE-03) system has patented multi-channel valves enabling simultaneous processing of up to 8 samples without having to use numerous solenoid valves and complex assembly. PromoChrom Technologies manufactures great products that are engineered for high reliability, reproducibility and repeatability. Moreover their designs is much more compact and cost-effective than competitors.
Automated sample extraction
We provide sample extraction and concentration solutions using integrated instrumentation that perfectly combines with GO-exHT automated clean-up systems. Solid and semi-solid samples can be easily and rapidly extracted with the Solvent Extractor – SER-158.
This automated extraction and concentration system uses the Randall principle, meaning extraction is performed in boiling extraction solvent. After this step, a second extraction step is performed using a hot soxhlet or twisselman extraction. Up to six samples can be extracted within 2-3 hours, using less than 100ml of solvent per sample. While extracting, the sample is simultaneously concentrated and extraction solvent is collected is a solvent recovery tank. After the extraction process has finished, only traces of the extracion solvent will be left, saving you time for concentration processes.
Concentration and evaporation solutions
Evaporation and concentration is needed to get rid of remaining extraction solvent after the extraction has finished. Also, after purification has finished the volume of the extract needs to be concentrated down to the desired end-volume for GC-injection. For these purposes we offer the CentriVap benchtop concentration system. This vacuum centrifuge can hold over 60 samples (2 ml vials) and uses a combination of heat and vacuum. The CentriVap can also be used as a standalone evaporator system for evaporation of larger sample sizes, up to 100ml. Different rotors for different sample volumes are available and can be very easily replaced.
Analytical standard solutions and mixtures
We supply a comprehensive range of certified analytical standard solutions and reference materials for the analysis of organic pollutants and contaminants, such as Dioxins, PCBs, PBDEs, PAHs, PCNs and pesticides. Custom made solutions and mixtures are also available upon request. Our standards and mixtures are produced by accredited manufacturers. (ISO 9001:2008; ISO/IEC 17025:2005 and ISO Guide 34:2009)
Specifically designed for GO-xHT, we offer a complete standard solution kit with sophisticated dilution scheme for the preparation of the calibration set, spiking solutions, clean-up standards and recovery standards.
In close cooperation with Nofalab in The Netherlands, DSP-Systems offers an extensive range of analysis of consumer and industrial goods as well as raw materials of food and feed products. Nofalab is a well known GMP+ and ISO 17025 accredited laboratory, equipped with the state of the art analytical instrumentation using the latest technology. Our comprehensive reports are internationally recognised, we make this service available to laboratories who wish to outsource (part of) their analysis, temporarily or for longer term.
We also assists laboratories with their method development and validation processes. A number of analysis we can assist you with are: Dioxins, PCBs, PBDEs, PAHs, pesticides, GMO, mycotoxin analysis, fatty acids and mineral oils.
