Contact UsEach of Sentry resin columns is designed to ensures plug-free flow and reduces channeling. Coming in a variety of sizes, you will be sure to find the correct column to meet your application.
- Each resin column comes with an initial charge of pre-measured color-indicating hydrogen-form cation resin.
- Optional auto shut-off quick disconnect kit with 1/4-inch ID tube connections available.
- Corrosion-resistant mounting clamps included with W7901x models.
- The RC-100 is specially designed to minimize the column's dead volume, assuring highly representative sampling. After a chemical upset, the RC-100 can produce a representative sample within four minutes (at a flow rate of 200 cc/min) while others can take as long as 16 minutes.
- In addition to reducing dead volumn, the RC-100 refillable ion exchange column's design also produces better flow distribution. Poor flow distribution and velocity can skew cation conductivity results by up to 0.1 µS/cm
- The RC-101 uses the same design but is made of PETG which is resistamt tp high levels of residual ammonia present in the sample or in the atmosphere near the column.
- The refillable, clear plastic column makes resin replacement economical and easy
- PETG columns are available for applications where chemical attacks may occur
- Provides optimum fluid velocity with increased resin efficiency
- Designed especially for flow rates common to water chemistry analyzers
- Minimizes lag time required to detect chemical upset
- No PVC used; wetted materials will not leach chlorides or plasticizers
- End fittings are 1/8-inch quick disconnects
- Refillable bags available for each column upon request
