Description
Depending on the degree of clean-up in the sample, if many impurities are absorbed into the column, a guard column is effective in preventing the contamination of the main column. Osaka Soda has two types of cartridge-type guard columns, one for general-purpose HPLC and the other for high pressure resistance UHPLC.
Guard Cartridge Column - For General HPLC
- Use with a holder and cartridge set
- The cartridge holder is the same for all cartridges with the same length, even if the inner diameter is different
- The main column can be protected by simply replacing the cartridge, which is available at a lower unit price compared to replacing the main column
- Can be connected easily by tightening with hand, no tools required
