MGB-500
VOC Gas Dilution System
|
| The
Merlin MicroScience manual gas dilution system
MGB-500 generates volumetric gas blends using
calibrated flow restricting orifices. Two gas streams may be
blended to any predetermined mixing ratio. The MGB-500
is a 100% type 316L stainless steel gas blender, without potentially
contaminating polymeric seals in any gas flow paths. The blender's
efficient operating principle can produce single step dilutions
of 1,000:1 while consuming less than 1.2 liters/min. total of
diluent gas. The inherent low gas consumption and high dilution
ratios obtainable can economically extend the use of common
"ppm" level calibration standards to the "ppb"
range. This dilution system is configured |
 |
| for
use with VOC standards and incorporates a humidification device
for the diluent to provide humidified VOC dilutions for calibration
of multi-component analyses such as the analysis of Ozone Precursors
in ambient air systems. It can also be equipped with relay activated
valves for the automatic introduction of check standards into
the analytical system. |
