The I.O.M. Sampler* IMPORTANT The I.O.M. cassette and filter paper combined must be pre and post weighed together for an accurate inhalable result The I.O.M. sampler is designed and closely adheres to the definition for inhalable dust given in EN481 I.O.M. - what does it stand for? The "Institute of Occupational Medicine". Based in Edinburgh, researchers at the Institute developed this sampler to overcome some of the difficulties encountered with other sampling devices.
Inhalable Dust Sampling using the I.O.M. Sampler For information on using the I.O.M. sampler for respirable dust fractions please contact SKC customer support on +44 (0) 1258 480188 Inhalable dust is taken to mean any solid particle which by its small size can be carried in an airflow or remains airborne. It includes the thoracic and respirable dust fractions. The inhalable dust fraction size is defined in the standard EN481. More information is also given in SKC’s Basic Step By Step Guide (224-G1).
Inhalable Dust Sampling using the I.O.M. Sampler type rotameter is usually marked with a number of dots. The dots give indication that the float is spinning in the airflow, thus showing that it is not touching the walls of the rotameter tube which could affect the accuracy of the reading. Note that the rotameter must be placed onto a flat, level surface to ensure that the float does not touch the sides of the rotameter tube.

The I.O.M. sampler complete with the new filter should now be fitted with the cassette cover supplied, and is ready to take into the workplace. cover and switch on the pump. IMPORTANT: The start time of the sample should be noted. New filter for sample Filter used for calibration 8. Mount the sample train (comprising the sample pump, tubing and I.O.M. sampler) onto the worker who is to wear it during the sample. The I.O.M.
Respirable Dust Sampling using the Cyclone Sampler Respirable dust is taken to be solid particles which, because of their extremely small size, can be drawn deep into the lungs, and are not ejected by the normal means of breathing out, coughing or travelling out in the lung mucus. It is because of this ability to stay in the body that it is considered to be dangerous. Dust of this small size is normally invisible to the human eye. The respirable dust fraction size is defined in the standard EN481.
Respirable Dust Sampling using the Cyclone Sampler fitted to the bottom of the cyclone sampler. Air Outlet 3. Connect the top tubing connector (air outlet) on the cyclone sampler to the inlet hosetail on the top of the sample pump using the length of flexible tubing. Retaining Ring Sampler Top 4. To set the flow rate required, in this case 2.2 litre/minute, a flow calibration device such as a Defender primary calibrator or a rotameter should be used.
Respirable Dust Sampling using the Cyclone Sampler tubing. Turn on the Defender primary calibrator and set it to take continuous flow readings. the required level. It is advisable to do this as quickly as possible to minimise the chance of collecting anything that may affect the final result. The cyclone sampler is now ready to take into the workplace. New filter for sample 6.
Respirable Dust Sampling using the Cyclone Sampler Once the pump is mounted on the worker in a satisfactory way it can be switched on. IMPORTANT: The start time of the sample should be noted. 10. At the end of the sample switch the pump off and note the finish time of the sample. Remove the sample train from the worker, and once away from the sample location re-check the flow rate of the sample pump (as per MDHS14/3).
Gas & Vapour Sampling using Sorbent Tubes • Tube adaptor for small diameter sorbent tubes (SKC You will need :- • • • • part no. 717-511) Sidekick sample pump (fully charged) • Two sorbent tubes from the same box or batch • Flow calibration device capable of measuring the Constant pressure controller (CPC) Low flow adaptor (tube holder) Tube cover of appropriate size for the sorbent tube being used • A length of flexible tubing 1.
Gas & Vapour Sampling using Sorbent Tubes the CPC should be on the side connected to the low flow adaptor and tube holder. 3. Take one of the sorbent tubes and break off both ends, ideally using a purpose designed tube tip breaker (such as SKC part no. 800-01200). Take care handling the tube as the broken ends are extremely sharp. Fit the sorbent tube into the short black hose of the low flow adaptor. 5.

At the end of the sample switch the pump off and note the finish time of the sample. Remove the sample train from the worker, and once away from the sample location re-check the tube flow rate.
Gas & Vapour Sampling using Impingers Impingers are typically run at a low flow rate of 1.0 litre/minute. It must first be decided if you are going to carry out personal or static sampling. If personal sampling is the method adopted you will require an impinger pouch and an in-line trap. If static sampling is more suited an impinger bracket and glass trap should be used.
Gas & Vapour Sampling using Impingers (Connect from the impinger to the in-line trap with a length of flexible tubing. It does not matter which way around the in-line trap is connected). 3. Fasten the bracket to the front of the Sidekick pump using the two screws supplied with the pump. Place the trap and the impinger into the bracket. (Place the impinger and in-line trap on a suitable surface). 4.
Bag Sampling using the Sidekick Pump Where there is a need for the sample not to come into contact with the pump or where the atmosphere may be aggressive (as found with stack sampling) a method of collection using an intermediate vessel is recommended. The intermediate vessel can be any container of adequate size that is air tight. For example, the SKC Vac-UChamber. Some people use large Tupperware containers if the bags are small, but any air tight vessel, metal, plastic or otherwise can be used.
The Sample Train The sample ''train'' is the name given to the combination of a pump, flexible tube and sampling device when connected together. It does not matter what kind of sampling device is attached to the pump as there are no specific terms for individual setups. The figures below give examples of sampling trains. Additionally the figure on the right illustrates the sample train during the process of calibration.
