Powders, granulates, direct sampling from bags and sacks organic liquids, solvents aggressive chemical and foodstuffs Liquids, aggressive chemicals/foodstuffs sampling without contact with pump PE, PTFE, PP, Al or stainless body PE and PTFE tubes Metal (stainless, Al, Titanium) PTFE, Polyamideįor sampling of gaseous samples or high vapour pressure gas/liquids Soft, paste-like substances (cheese, butter, soap) The list is therefore not exhaustive and other sampling tools may be used according to the nature of the goods to be sampled.įor dividing or reducing aggregate samples of granular productsĭeep-frozen foodstuffs and semi solid substances The availability and design of sampling tools may vary in different Member States. The table includes the sampling tools suitable for different types of goods. Cords, ropes and chains used for sampling of extremely flammable liquids must be made of materials which prevent static electricity being generated. The sampling tools used for taking samples from liquids in depth must be tied to a cord, rope or chain long enough to take samples from any level required. They must be made of sufficiently electro-conductive materials to prevent static electricity being generated and must not create sparks when in contact with another metal object. The sampling tools intended for the sampling of petroleum products, organic solvents and other easily flammable liquids and gases must be approved for such use. Other general tools may be useful during sampling, for example knife or box cutter, scissors, tongs, cleaning brushes, adhesive or sealing tape, pen, flashlight, etc. When lowering dipping vessels various manually-operated reels and lowering and raising cables may be used. For this purpose, various plastic or metal boxes, drums, canisters, buckets, etc. Other tools may be used for the aggregation of primary samples or for the homogenisation, separation, reduction, quartering, etc. Other suitable tools, similar to the ones described above, may also be used for sampling purposes, provided that they are able to perform the operations described and meet the safety requirements. Sample cylinder is an assembly that includes a pressure rated cylinder and inlet and outlet isolation valves. Sampling gases: Sampling require a metal cylinder ( sample cylinder) for collection and transport. Sampling solids in powder or granulated form: The following tools may be used: spear samplers, tube-type samplers, zone samplers, sampling trowels, spiral samplers, samplers for frozen goods, hand-drill samplers, etc. Sampling liquids: The following tools may be used: vacuum pumps, dipping vessels, pipette-type samplers, sampling scoops, piston-tube samplers etc. After use, you must clean the sampling tools according to specific instructions. You must always check their cleanliness before use. they must also conform to safety requirements.the effects of the goods being sampled (e.g.all parts must be made of materials resistant to:.they must be robust enough to withstand handling operations.Sampling tools must meet these general requirements: All sampling tools must be designed and manufactured so as to serve their intended purpose and preserve the original characteristics of the sampled goods.
