Introducing the latest advancement in Inhalable Sampling

disposable inhalable sampler air quality technician

The Zefon Disposable Inhalable Sampler (DIS) is a unique inhalable sampler with a physical design to replicate the collection of the original inhalable sampler (designed by the Institute of Occupational Medicine (IOM) in Scotland) at a flow rate of 2 LPM. This sampler uses a lightweight, one-time filter capsule and sampling head. This saves time and money by eliminating user assembly, sampler cleaning, and the possibility of cross-contamination. The DIS is available with several different types of filter capsules, including ones suitable for gravimetric analysis or completely digestible capsules for metals analysis.

How Our DIS Works

Using our disposable inhalable sampler first requires calibration to ensure sampling accuracy. The steps in the calibration process include:

  • Inserting the DIS into the calibration adapter and tightening the thumbscrew
  • Connecting the sampler's outlet port tubing to the pump's inlet fitting
  • Attaching the tubing to the adapter's brass hose barb as well as the opposite end of the calibrator
  • Starting the pump and adjusting the flow rate to attain a calibrator reading of 2/L min

After calibration, you're ready to start sampling. The process entails:

  • Verifying that the pump calibration matches the method flow rate
  • Using the clip to attach the DIS sampler to the employee's lapel to ensure proximity to the breathing zone
  • Removing the red outlet plug
  • Connecting the tubing from the inlet of the worker's sampling pump to the DIS sampler's outlet
  • Removing the cap from the sampler inlet
  • Sampling for the length of time specified by the desired application
  • After sampling, using the cap to cover the sampler outlet and inserting the red plug into the outlet
  • Placing the sampler into an appropriate bag and shipping it to the lab for analysis

Disposable Inhalable Sampler Applications

  • Applications of our DIS include:
  • ACGIH definition of inhalable particulate matter
  • NIOSH Method 5700 for particulate formaldehyde
  • British Method MDHS 14/3 for inhalable dust in air
  • British Method MDHS 14/4 for sampling and gravimetric analysis of respirable, thoracic and inhalable aerosols
  • British Method MDHS 25/3 for organic isocyanates in air
  • British Method MDHS 6/3 for lead in air
  • Australian standard for inhalable particulate
  • ISO/CEN for bioaerosols (health-related fractions)

DIS Features and Benefits

A disposable inhalable sampler for sale from Zefon International includes a host of features and benefits that simplify the sampling process, increase accuracy and reduce costs:

  • Preloaded, ready to use
  • No more assembly errors from mismatched parts from different brands or versions of samplers
  • No more cleaning samplers or cross contamination
  • No more transport clips to worry about
  • No more expenses from sampling heads getting lost or misplaced
  • Lower tare weight provides better sensitivity
  • Accounts for wall deposits as recommended by NIOSH
  • Collection and performance matches that of the original inhalable sampler designed by the Institute of Occupational Medicine (IOM) in Scotland.
  • Leak-free design

Choosing a Disposable Inhalable Sampler Over a Reusable Inhalable Sampler

Two types of inhalable samplers are available: disposable and reusable models. A reusable version features a lower unit cost, and the fact that you can wash it and use it repeatedly translates to lower long-term ownership costs. On the downside, reusable samplers require frequent care to ensure they remain free of contaminants.

It's also possible that workers can make a mistake when pre-assembling the cassettes, as well as when matching the cassette with the correct filter or back. Another potential risk is that users could attach the wrong clip when shipping the cassettes to the testing lab, which could produce inaccurate sampling results.

Perhaps the most important advantage of choosing a disposable inhalable sampler is that the cassettes come already loaded, which eliminates the hassle of assembling them and prevents errors. You also won't have to worry about cleaning or caring for the cassettes, which saves time and substantially reduces the risk of contamination. What's more, disposable inhaler samplers weigh less than their reusable counterparts, which can enhance testing results and improve sampling accuracy.

The only significant disadvantage of using disposable inhalable samplers is that they might not provide the most cost-effective solution for sampling operations that have the resources and equipment to manage the handling and control process with efficiency.
