Abstract
Disclosed herein are volatile organic compound monitoring or detection systems and methods, including systems having both a reference air intake component and at least one air sample intake line. In certain embodiments, the systems provide for continuously repeating cycles of testing and calibration/recalibration. Further implementations relate to systems having two or more intake lines that can be positioned to take air samples at distances ranging from 5 feet to 200 feet or more apart.
Claims20
A volatile organic compound (“VOC”) monitoring system comprising:
- (a) a housing;
- (b) a reference air intake component associated with the housing, the air intake component comprising an intake air purification device;
- (c) an air sample intake system associated with the housing, the air sample intake system comprising at least one sample intake line;
- (d) at least one valve coupled to the at least one sample intake line and the reference air intake component;
- (e) an air pump fluidically coupled to the reference air intake component and the at least one intake link via the at least one valve;
- (f) a detection assembly fluidically coupled to the air pump;
- and
- (g) an exhaust component associated with the housing, the exhaust component comprising an exhaust air purification device fluidically coupled to the detection assembly.

- (d) a detection assembly coupled to the intake air purification device and the sample intake system, the detection assembly comprising:
- (i) an illumination lamp;
- and
- (ii) a photon-sensitive sensor;
- (e) an air pump coupled to the intake air purification device, the sample intake system, and the detection assembly;
- (f) an exhaust component comprising an exhaust air purification device coupled to the detection assembly;
- and
- (g) a controller electronically coupled to the detection assembly.

A method of monitoring VOCs, the method comprising:
- positioning a VOC monitoring system such that the VOC monitoring system can receive samples from a target volume, wherein the VOC monitoring system comprises:
- (a) an intake air purification device;
- (b) at least one sample intake line;
- (c) a detection assembly coupled to the intake air purification device and the at least one sample intake line;
- and
- (d) a controller coupled to the detection assembly;
- calibrating the system by causing a calibration sample to pass through the intake purification device and the detection assembly, measuring a first zero reference reading with the detection assembly, and transmitting the first zero reference reading to the controller;
- testing an air sample by causing the air sample to pass through the at least one sample intake line and the detection assembly, measuring a sample reading with the detection assembly, transmitting the sample reading to the controller, and calculating a VOC concentration with the controller based on the sample reading and the first zero reference reading;
- recalibrating the system by causing a recalibration sample to pass through the intake purification device and the detection assembly, measuring a second zero reference reading with the detection assembly, and transmitting the second zero reference reading to the controller;
- and
- repeating the testing and recalibrating steps.
