As a result of our efforts in research and development and the continuous improvements in our manufacturing techniques we present OPTIMA® – a series of high performance capillary columns for gas chromatography.
OPTIMA® capillary columns provide:
High thermal stability
High-boiling solutes (with very low vapour pressures) "normally" have very long retention times and rather broad peak shapes. OPTIMA® columns with their increased operation temperatures elute high-boiling compounds faster and with better peak shapes.
Maximum operating temperatures for OPTIMA® phases
The first temperature is valid for isothermal operation, the second for short isotherms in a temperature programme.

Reduced column bleed
Less column bleed yields increased sensitivity and accuracy through a better signal to noise ratio for any kind of detector. Reduced column bleed improves detectability of solutes in qualitative and quantitative GC-MS analyses.
More inert columns due to optimised deactivation
Polar compounds are frequently difficult to analyse, because they often give broad tailing peaks. Advances in deactivation technology for the OPTIMA® capillaries result in an excellent chromatographic performance yielding improved peak shapes of polar compounds combined with improved efficiency and sensitivity.
For controlling quality MACHEREY-NAGEL determines the following parameters:
- efficiency by measuring the separation number in a temperature programme.
- polarity by measuring retention indices
- bleeding in a temperature programme with a test mixture including high-boiling hydrocarbons
- inertness by measuring the peak height ratio for decylamine/ C-12 (for non- to medium polar phases)
