Built-In Guard Column, No Connections
Guardian columns have the 2 m, 5 m or 10 m guard built directly into the analytical column in one continuous length of tubing. Guardian system provides the same inert column protection, but eliminates the possibility of leaks
Key Features
- 2 m, 5 m or 10 m guard built directly into the analytical column in one continuous length of tubing
- Same inert column protection as a separate guard, with no possibility of leaks
- Non-volatile contaminants deposit on the Guardian section, preserving the stationary phase
- Easier to trim contaminants off the front of the column
Recommended Use
As temperature increases (oven ramp program), the sample is vaporized and moves unretained through the Guardian section of the column. Non-volatile contaminants are deposited on the Guardian section, better preserving the stationary phase and making it easier to trim contaminants off the front of the column.
