Automated sample preparation system DRQ-B

for chromatographyfor sample preparationdilution

Product overview
The final stage of sample preparation before chromatographic analysis often requires concentration and filtration. Manual nitrogen blow-down methods require continuous operator attention and are time-consuming. The RayKol DRQ-B integrates concentration, internal standard addition, volume adjustment and filtration into a single automated workflow, enabling unattended batch processing and reducing the risk of human error. The system is suitable for pesticide residue testing, veterinary drug residue analysis and routine chromatographic sample preparation.

Key features

• Batch processing up to 60 samples
• Dual capping compatible with 15 mL and 2 mL vials
• Visual endpoint detection for nitrogen evaporation
• Integrated one-step workflow: concentration, internal standard addition, volume adjustment, filtration
