Variable split sampler for air monitoring |
| abstract |
An apparatus for controllably varying the sample volume for each of a plurality of sample lines used with air monitoring equipment is disclosed. The sample volume is varied depending on the compound or compounds of interest sampled through each line. The flow volume from each sample line is determined and controlled by proportional time that an electrically actuated valve is open for that sampling line. |
