Suppression plays a key role in ion-exchange chromatography and conductivity detection. It is widely used, e.g., for the analysis of anions and organic acids.

Metrohm is pleased to present a new brochure putting the theoretical aspects and practical benefits of suppression in ion chromatography in a nutshell.

Suppression as a practical solution for ion chromatography

• decreases the background conductivity of the eluent
• minimizes baseline noise
• optimizes the signal-to-noise ratio
• increases the sensitivity of the measuring system

Genevac announces a proprietary “odour reduction” function for its EZ-2 evaporator which enables it to be sited on the open bench rather than taking up valuable fume hood space.

Many solvent evaporators are routinely sited inside fume extraction hoods because residual solvent vapour, remaining in the chamber at the end of a run, can expose the operator to potentially harmful odours when the system is opened. The EZ-2’s Reduce Odour function automatically adds a repeated vent and vacuum cycle to the end of a method, which purges the evaporation chamber of residual solvent vapours...
