Extraction

The LABSOLUTE® extraction thimbles are made of 100 % cellulose. They have a high mechanical stability and are free from binders. The extraction thimbles have a wall thickness of about 1 mm and a pore size of approximately 5 µm. They are perfect for all kind of Soxhlet extractions as well as for the separation of liquid and solid particles out of air and gases.

Neutral and fat free. With excellent retention capacity. Ash content <0.1 %.

Extraction and clean-up mixtures for sample preparation in the pesticide analysis of vegetable foodstuffs according to EN 15662 using GC/MS or LC/MS after acetonitrile extraction and purification using the dispersive SPE-QuEChERS method.

The samples are first extracted with Mix A. Purification is done with one of the following mixtures:

• Mix B (Clean-up mixture for fruits and vegetables with low fat content, e.g. apples, strawberries)
• Mix C (Clean-up mixture for fruits and vegetables with high fat content, containing oil/wax, e.g. avocados)
• Mix D (Clean-up mixture for moderately chlorophyll/carotenoid-containing fruits and vegetables, e.g. carrots, salad)
• Mix E (Clean-up mixture for fruits and vegetables with high chlorophyll/carotenoid content, e.g. sweet peppers, spinach)

If required, add ceramic homogenising beads for better mixing.

• Mix A contains a bag with the required amount of mixture and a 50 ml empty tube
• Mix B, C, D and E are pre-weighed into a 15 ml tube

• Fat determination in food and feed
• Determination of binder content in asphalt
• Analysis of soil contaminants
• Determination of additives in rubber and elastomers

They are ideally suited for:

• total crude fibre determination (part of the Weender animal feed analysis as performed in Europe)
• neutral detergent fibre and acid detergent fibre determination (NDF and ADF according to Van Soest)
• acid detergent lignin determination (ADL according to Van Soest)
• different fractions of fibre (cellulose, hemicellulose and pectin) behrotest^® semi-automatic crude fibre extraction units simplify everday life in the lab:
• Easy operation
• The analyst is guided through the procedure by messages on the display.
