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

behrotest^® Standard-Aufschlussgefäße haben Standardmaße. Das heißt sie passen in Aufschluss- und Destilliergeräte der meisten Hersteller. Das heißt auch, dass Standard-Aufschlussgefäße der meisten Hersteller problemlos in unsere behrotest^® Wasserdampfdestillierer passen.

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.
