Frequently Asked Questions
1. What is the role of PSA/GCB in sample clean-up?
PSA (Primary Secondary Amine) removes organic acids and sugars, while GCB (Graphitized Carbon Black) removes pigments like chlorophyll, making them ideal for vegetable and fruit sample preparation.
2. Can I use CHROMABOND columns for large volume extractions?
Yes, Macherey-Nagel provides large-volume reservoir columns, such as the 70 mL models, designed for high-capacity sample loading and processing.
3. What are ceramic homogenizers used for?
Biocomma ceramic homogenizers are added to centrifuge tubes to increase the efficiency of sample breakdown and salt dispersal during the initial QuEChERS extraction step.
4. Are SPE columns available in empty configurations?
Yes, we offer Macherey-Nagel Chromabond Empty Columns (e.g., 15 mL PP), allowing researchers to pack their own specialized stationary phases for custom extraction methods.
