Separation column
The intelligent separation column separates different components accord-
ing to their interactions with the column. Metrohm separation columns
are equipped with a chip where their technical specifications and history
(start-up, operating hours, etc) are stored.
1.2 Intended use
The 940 Professional IC Vario ONE/HPG is used for the determination of
cations and anions without suppression using ion chromatography when
the complex separation problem requires the use of gradients.
The second high-pressure pump in the lower plug-in allows for the con-
trolled mixing of two eluents.
The present instrument is suitable for processing chemicals and flammable
samples. Usage of the 940 Professional IC Vario therefore requires the
user to have basic knowledge and experience in handling toxic and caustic
substances. Knowledge with respect to the application of the fire preven-
tion measures prescribed for laboratories is also mandatory.
