074-594-P1H Micro GC Fusion Operating Manual 39 / 319
Separation is influenced by:
• coating type
• thickness
• length
• diameter
• carrier gas
Separation may be further optimized by adjusting:
• column temperature
• column head pressure
Temperature ramping provides additional control of component separation, compared
to isothermal operation. With temperature programming, light components can be
separated at low column temperatures. The column temperature can then be ramped
to increase the elution speed of heavier components.
5.7.3 Detection
Micro GC Fusion uses a MEMS based µTCD and has a detection range from low ppm
to high percent.
The Fusion Auto-Sensing Technology (FAST) Enabled detector system automatically
adjusts detector gain during a single sample run, effectively eliminating the need of
two sensitivity settings when analyzing low ppm and high percentage in the sample.
The FAST Enabled Micro GC Fusion is proven to provide excellent linearity over ppm
to high percent component concentrations, allowing fast and accurate analyses of
gases over a large concentration spread.
