Air Monitoring - UK Focus xxvii MCERTS Award for VOC Emissions Analyser
Quantitech has announced that the Sick 3006 portable VOC monitor has a new MCERTS certifi cate, valid to July 2019. The company’s Dominic Duggan says: “This is important news for any process that needs to report total hydrocarbon emissions data; MCERTS is essential for monitoring Part A processes, however, as a portable instrument, the 3006 is also ideal for Part B processes and stack testers in a wide range of industries.”
The certifi cate confi rms that the 3006 instrument complies with: MCERTS Performance Standards for Continuous Emission Monitoring Systems, Version 3.4 dated July 2012 EN15267-3:2007, and QAL 1 as defi ned in EN 14181: 2004.
Completely self-contained, with its own air and gas supplies, the 3006 is a heated total hydrocarbon analyser for monitoring combustion and ventilation stacks from 100ppb to 100,000ppm. Employing a patented miniature heated sensor block with a fl ame ionisation detector (FID) controlled up to 240°C, the 3006 can be used to monitor steam saturated gases.
The fi eld tests for which the 3006 is certifi ed were conducted with both fuel gas options – Hydrogen and Hydrogen/Helium mix. However, Hydrogen is by far the more preferable option because it is signifi cantly lower in cost and the 3006 operates at very low fl ow rates (20cc/min).

The SKC Dust Kits are ideal for workplace sampling for dusts from metals, woods, foodstuffs, stone, cement and others. The kits include the small and lightweight IOM Sampler for inhalable and respirable dusts, which closely simulates the way in which airborne particles are inhaled through the nose and mouth. A Cyclone is also included, specifi cally designed for respirable dust which eliminates the effects of ambient wind speed and orientation. Complete the kit with our extensive range of pumps.

The EPAM-5000 is an easy to use, complete portable solution for environmental monitoring of particulates. Supplied in a compact, rugged, watertight carry case with a choice of a PM10, PM2.5 or PM1.0 sampling head the internal sample pump can operate for up to 24 hours on one battery charge or continuously using the AC adaptor.
Also, available in the SKC range is the DPS Kit for ambient PM10 and PM2.5 sampling. Supplied in a compact, heavy duty lockable case it meets the needs for monitoring remote locations or indoor air sampling. The kit includes the sample pump, providing 24 hours continuous monitoring, and everything else you need including a sampling head, fi lter cassettes, calibration adaptor, charger and tubing.
Isokinetic Source Sampling
For More Info, email: email:
Obtaining a representative sample of particulate matter from a gas stream requires a more complex procedure than sampling only for gases. Representative sampling requires that the velocity of the gas/particle mixture passing into the sampling nozzle must be as close as possible to the velocity of the gas stream in the stack or duct. When the velocities are the same, the sampling is isokinetic. During the entire sampling period, the stack velocity must be monitored constantly and the pumping rate adjusted so that the nozzle intake velocity matches as closely as possible the velocity of the in-stack gas/particle mixture. In addition, the pumping rate needs to be adjusted for differences in pressure, temperature and moisture between the stack conditions and the pump or meter console.

Stationary source sampling is conducted to evaluate gas stream emissions to the atmosphere from stacks, ducts or process exhausts. A pollutant’s concentration is measured by extracting a known volume from the gas stream and determining the average stack gas fl ow rate over the sampling period. The mass emission rate of each constituent then may be calculated.

Air sampling is commonly carried out to ensure that workplace or environmental air is meeting regulatory standards and to help Occupational Hygiene and Health & Safety professionals assess employee exposure to airborne hazards, especially particulates. With 50 years of leading the world in air sampling technologies, SKC can offer a range of kits to suit both workplace and environmental particulate sampling.
