PURELAB® flex 5 & 6

A unique automated solution for Ion Chromatography.

Switch on and walk away, Ion Chromatography made easy.

A standalone Ion Chromatography and water purification system all-in-one. The PURELAB flex 5 & 6 is designed to couple directly with the Metrohm 941 Eluent Production Module. This combination delivers complete automation. No need to monitor eluent concentration make-up, no need to refill or to set reminders to refill the water.

• Integral built-in reservoir for pressureless ultrapure water supply Combinable for any existing IC Setups

- developed for Metrohm Dosino technology

• Closed system avoids eluent contamination due to water handling and exposure

• Monitor water purity via USB datalog ensuring analytical performance during test batch

• Prevent column clogging and increases column life: UV

(185/254 nm) ensures bacteria and organics control

• Stable retention times: no dissolved CO in water prevents 2

pH change

• 881/882 Compact IC

• Enhanced detection limits through improved stability and purity

• 850 Professional IC

• 930 Compact IC Flex

• Simultaneous multi-usage: eluent generation, system rinsing and general laboratory work

• 940 Professional IC Vario

• Reduces eluent preparation to minimum compared to using bottled water

This unique Ion Chromatography solution is produced by two of the world’s leading manufacturers: Metrohm, market leader titration and voltammetry and a leading manufacturer for Ion Chromotography and ELGA®, market leader in innovation and design for laboratory water instruments.
