MMSD Digital
Gas Dilution System
|
| The
Merlin MicroScience manual gas blender MMSD
generates volumetric gas blends using calibrated flow restricting
orifices. Two gas streams may be blended to any predetermined
mixing ratio. The MMSD 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 10,000:1
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 "sub-ppb" range. This
dilution system may configured for use with VOC standards and
incorporate 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. The system can also be configured for use in high purity
gas systems providing less than 10 ppb atmospheric contaminants.
Systems can be calibrated for single gas matrix or multiple
gas matrices upon request. |
