Frequently asked questions

What are the benefits of implementing capillary column backflushing?

It allows for more samples per day, reduces gas and power usage, lowers costs, extends column life, and improves data quality.

What is a downside of using coated pre-columns for backflush?

They are more expensive to replace than uncoated columns and require longer backflushing times.
