Gain great flexibility with an intelligent collection concept


By: Susanne Feifel

When it comes to ultra-trace analysis larger sample amounts are required to reach lower detection limits. Typical examples are ultra-trace analysis of food samples with a demand for representative sample amounts, e.g. food contact materials penetrating into food, or dioxins/furans determined in poly urethane foam being used for air monitoring tasks of living rooms or industrial facilities. Whenever solvent amounts of more than 150 mL per samples are collected, evaporation with the standard 220 or 240 mL collection vessel may be limiting.

With SpeedExtractor’s flexible collection concept you are able to accommodate a selection of different collection vessels which allow for transfer free evaporation and concentration of extracts.



Application Note #64: Determination of Pesticides in Spices By Extraction

Determination of Pesticides in Spices

Determination of Pesticides in Spices

Application Note #64 describes a fast and reliable way to extract organochlorine and other pesticides in chilli and paprika spice samples with the SpeedExtractor E-916. After the extraction the extract was cleaned up via GPC and analyzed by GC-MS/MS. Contact us to request this Application Note.

A pesticide is any substance or mixture of substances intended for preventing, destroying, repelling or mitigating any pest. Pesticides can be classified by their chemical structure (organochlorines, organophosphates and carbamates) or by their target (herbicides, insecticides, fungicides, rodenticides, pediculocides and biocides).

The adverse health effects depend on the type of pesticide. Organophosphates and carbamates for example affect the nervous system. Others may irritate the skin or eyes. Some pesticides may be carcinogens. Others may affect the hormone or endocrine system in the body.

SpeedExtractor E-916 with 20 ml cells, GPC Gilson 233XL, Varian 3800 with MS-1200 QQQ

Paprika and Chilli Powder with incurred pesticide content.

3 g sample was weighed in a beaker and 6 ml of water was added. The mixture was placed in the refrigerator over night. The next day 3 g of diatomaceous earth was added and mixed in well.

The sample was transferred into a 20 ml extraction cell. A fourfold extraction was carried out using the parameters shown within the Application Note. A blank and a spiked sample were extracted as well (QC test). After the extraction a GPC clean-up was performed and the pesticide content was analysed by GC-MS/MS. For comparison the samples were also extracted with a Dionex ASE® 200.

New Products
The first stand-alone FT-NIR for Food and Feed industries: NIRMaster
This breakthrough instrument is the first stand-alone FT-NIR spectrometer which has been specifically designed with hygiene in mind for routing QC work in harsh environments in Food and Feed industries. Available in polymer and stainless steel housings, it includes a built-in PC loaded with a variety of ready-to-use calibrations.

Feature Products
Efficient and safe spray drying of aqueous and organic solutions with the B-290 Mini Spray Dryer

The B-290 is a bench-top system for quick and easy drying of aqueous solutions and suspensions, as well as organic solutions, with the optional Inert Loop B-295. This instrument is not only useful for feasibility studies, but also to produce small samples of dried product. Its easy operation facilitates obtaining optimized processes within a short time.

Minimize time between sample analysis and result generation with the SpeedExtractor

Despite modern extraction techniques, the process can be very time consuming. Thanks to the SpeedExtractor’s parallel format, up to six samples can be extracted simultaneously in approximately 20-40 minutes. As a result, incoming batches can be processed immediately and the analysis result made available on the same day, even if subsequent extensive purification steps are required. This allows for a previously unheard level of efficiency and throughput: up to 96 samples in one work day!
