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

Workstation model SMA-ARB

The behrotest^® workstation model SMA-ARB is a basic system for simultaneous aqua regia digestion of either 6 or 12 samples for heavy metals analysis.

System components:

• Precision 6 or 12 sample SMA heating block for round-bottom sample vessels of Ø 41.8 mm, temperature range 20 to 300 °C.
• External ET 2 controller, operating range 20 to 399°C. Time settings from 10 to 120 min. and continuous operation.
• 6 or 12 SR 2 250 ml round-bottom sample vessels with standard taper mouth and PVDF collar.
• 6 or 12 RFK 1 Allihn reflux condensers.
• 6 or 12 AS 1 absorption vessels.
• SG/B stainless steel vessel holding frame for 6 or 12 sample vessels.
• Support scaffold with cooling water distributor and storage holder for 6 or 12 condensers.

Workstation model SMA-ARM

The behrotest^® SMA-ARM workstations are provided with a programmable microprocessor-controlled time/temp. controller as well as a fume manifold for drawing off the acid vapors. This results in greater convenience and functionality in routine laboratory operations.
