Field Filtering Samples for Dissolved Metals Analysis | SVL Analytical, Inc.
To help our clients in the selection of field filtering apparatus and supplies we provide the following information and links.
A peristaltic pump (also called a circulating pump or vein pump) and appropriate hosing is required with a 0.45µ filter capsule and sample bottle to collect samples.
The filters or disposable capsules may be referred to as "QuickFilters" (QED Environmental System), "Dispos-a-filters" (Geotech Environmental Equipment), or Groundwater Sampling "Capsules".
Filters come in multiple capacities: for example QED offers the FF 8100 (standard capacity) and the FF 8200 (high capacity) QuickFilters. Hi capacity filters are better suited to sampling waters that are silty or particulate-laden.
Users should check the vendor sites for specifications to ensure the background levels of contaminants meet their requirements.
The filters are approximately $7.00/std capacity filter and up to $30 or more for high capacity filters. They are designed to be used once and disposed, so they are an expensive consumable if many samples are to be collected.
The pump can run on 115v from a generator in the field, or, by 12v with a cigarette lighter plug for your vehicle.
All these items can be purchased directly from the vendor.
