Residual Life Indicator for Physical Adsorption Capacity of NBC Filters. Part 1. Acetone Vapor Pulses and the Effect of Moisture Content on Retention Characteristics
Abstract
Currently, no method exists to indicate when chemical biological radiological nuclear (CBRN) filters no longer have the capacity to protect the warfighter in the event of a toxic chemical release. The three factors responsible for CBRN filter failure are losses of mechanical integrity, physical adsorption capacity, and of reactive capacity. In this report, data are collected to support the development of a residual life indicator for the remaining physical capacity of a CBRN filter using acetone as a pulsed chemical tracer. Specific areas of focus include relationships between elution characteristics, relative humidity, pre-adsorbed moisture, and pre-adsorbed organic contaminants.
