Introduction to Sampling

CRP is a world leader in the design and manufacture of safe and representative

sampling systems for use in Pharmaceutical, Chemical, Food and Beverage, Biotechnology, Pulp and Paper, Petrochemical & Semiconductor industries.

We offer a wide range of sample dispensing options and secondary containment solutions to suit the process. All levels of sophistication are available from simple manual sampling to remote automated sampling and analysis systems. All our sampling systems are designed with operator and environmental safety as the primary consideration

Toxic, flammable and corrosive medias are safely sampled using systems with all wetted parts in PTFE, PFA, Hastelloy and other exotic materials. Sampling systems are also available in 316L Stainless steel for less corrosive duties.

We pride ourselves on "the first sample being the right sample."

What is "Representative Sampling"?
A sample taken from a process pipeline or reactor must truly represent the exact constituents of the process without any contamination. Contamination of a sample can create incorrect test results and cause further process problems. Contamination of samples can be caused through reaction with the environment, but is more often caused by traces of the previous sample being held up within the sampling system. CRP's range of samplers have several design features built in to overcome contamination problems and provide that important representative sample the first time - every time.

Traditional methods of sample taking have been rather crude and rudimentary. They have included open ended valves which have been allowed to flow into effluent drains to run clear any old product before flowing representative enough to take a sample. Or taking a first sample and discarding it before a second representative sample is taken. These traditional methods incur a lot of costs and can be environmentally unfriendly. Operator exposure is of great importance too and may require the use of expensive safety equipment and clothing. By using a representative sample the operator need only take the volume of sample required to carry out their tests, typically this can be only a few millilitres. Meaning far less spent sample media to dispose of saving additional costs.

The costs involved in treating effluent and disposing of excess sample volumes is becoming increasingly more expensive. Government legislation is more restrictive and greater emphasis than ever is being placed on the environment. Taking just enough sample volume as required saves in these expensive reprocessing costs. CRP also offers various levels of containment for our sampling systems to reduce and prevent uncontrolled spillages and pollution from the sampling process.

Operator Safety
Process samples come with many types of potential hazard to the operator; Samples can be very hot, corrosive or toxic or all three. The operator must not be exposed to these dangers. We can offer sampling solutions to effectively protect the operator from these hazards. This can often mean that expensive safety equipment and personal protection equipment such as breathing apparatus etc. which can take a long time to put on and use are no longer necessary.

Sample media cost savings
In today's modern pharmaceutical world manufacturing processes can be extremely expensive with a few grams of process media costing several thousand pounds to create. Likewise within the fine metal reprocessing industry a few millilitres of sample can be worth a significant amount. It is very beneficial to take a very small representative sample from these processes to save wastage costs.

Where samples are expensive in their own right, corrosive or toxic or a hazard to the environment or operator CRP has a sampling solution to minimise the costs involved in taking a process sample.
