HERBS & SPICES
What we offer:
Extraction of Pesticides
Pesticide testing is crucial to assessing the safety of fruits and vegetables for consumption. The traditional extraction method for pesticides from produce is the QuEChERS method. This method is tedious, manual, time consuming, and wasteful. Thus, there is a need for improved methods of extraction. The EDGE®, in combination with Q-Matrix™ Hydra, a waterremoving sorbent, can be used to extract a panel of pesticides from 10 g of homogenized cucumber, tomato, and green pepper in less than 9 minutes. The recoveries of the pesticide panel were greater than 70% for each matrix tested, and these results were highly reproducible. The EDGE provides a fully automated extraction that combines both the sample and sorbent into one sample vessel, alleviating the human burden of extraction and the need for multiple sample transfers.
Polycyclic Aromatic Hydrocarbons (PAH) are a major class of organic hydrocarbons that originate from both natural and anthropogenic sources. They must be tested due to their mutagenic, carcinogenic and toxic properties. PAH extractions are done using the Soxhlet method with typically large amount of solvents and long extraction times. The CEM EDGE automated extraction system, was used to extract PAHs from different food samples. All matrices were extracted with excellent recoveries up to 90% or higher.
The EDGE uses small solvent volumes, typically 35ml, with a total extraction time of only 10 minutes.
The EDGE is an ideal choice for food and environmental laboratories with different sample types and wish to implement automation in their workflow.
Clean, economical and efficient metal digestions
The Environmental Express Hotblocks have revolutionized the way laboratories think of metals digestions. With these HotBlocks, laboratories can now perform digestions of samples under uniform temperature conditions up to 96 samples at a time. The HotBlock is made of a PTFE-coated graphite block within a Kydex® housing with no exposed metallic parts reducing corrosion potential from the highly acidic environment. The HotBlock® utilizes our disposable polypropylene digestion tubes for all EPA approved metals digestions, allowing laboratories to eliminate the washing of glassware.
Automation of the sample prep steps in the laboratory is oftentimes key to a laboratory's overall success. With the introduction of the AutoBlock, we have truly automated the metals digestion process. Users no longer have to manually add acid and reagents to samples, set timers to turn off heat, or manually adjust temperatures based on various method requirements.
The intelligent sample preparation for your elemental analysis
CEM Mars 6 is the easiest, safest and most intelligent microwave digestion system on the market.
It is the only system that uses integrated sensor technology to recognize the vessel type as well as the sample number then apply the appropriate amount of power to ensure the highest quality digest. With options for remote system control and contactless all vessel temperature control, the MARS 6 is ready to handle your most difficult samples.
iLink: Monitor and control your Mars 6
With iLink you will be able to operate and monitor your MARS 6, or multiple MARS 6 systems, and get the results on your mobile device. You’ll be free to move around in the lab and free to focus on other tasks.
Sterilisation and Pasteurisation
It is important that the food industry ensures that its products meet the highest standards of microbiological quality.
What is sterilisation?
Unlike pasteurization, the sterilization process seeks the elimination of all microorganisms, pathogenic or not, that reside in fresh foods and cause their decomposition, by treatment at temperatures above 100ºC.
In this case, the food is heated from 120ºC to ultra high temperatures (UHT) of 140º, to cause the death of the microorganisms and their spores. Because microorganisms do not survive, sterilized products have a longer shelf life than pasteurized products, although its disadvantage is that it can affect the quality of some products.
What is pasteurization?
Pasteurization allows the elimination of microorganisms that cause food adulteration. It is a thermal treatment to reduce the microbiological load of liquids and solids, controlling the temperature and time of the process. It consists of heating a food to temperatures below 100ºC for a brief period of time and cooling it quickly, during times and temperatures that vary according to the type of product, its format or type of packaging.
