Samplers
Drawing process samples in open containers invites contamination and inaccuracy, and also poses serious health, safety and environmental risks.
Due to the growing complexity of the industrial processes in general and more specific for processes in the (petro)chemical and pharmaceutical industries, the need for tests and analyses increases continuously. The need for representative samples plays a critical role in ensuring product verification. Yet sampling directly from the process often includes the risks of exposure to the operator, as well as contamination and pollution to the environment.
Introduction to Sampling - This sampler solves the problem of taking samples of toxic, dangerous and volatile substances. it has the following advantages
Safer for the operator
Safer for the environment
Safer for the sample (representativity)
Easy operation
Economical
Low maintenance
Minimal pollution/contamination

Sampling Systems: Maintaining Quality and Safety -The need for representative samples plays a critical
role in ensuring product verification. Yet sampling
directly from the process often includes the risks of exposure to the
operator as well as contamination and pollution to
the environment. The DOPAK® sampling method reduces such risks
with its patented design and simple method of operation.
The bulletin also includes details of sampling in bottles and cylinders. In addition many applications are detailed.

Containers - This link covers;
- Sampling in bottles - A sample is
drawn from the process and arrives at atmospheric pressure in the sample
container.
- Sampling in containers
- A sample is drawn from the process and arrives at process pressure in the
sample container.

Powder or Granule Stream samplers - These samplers can be used to sample almost any powder or granule stream by either a composite, batch or grab sample. The design prevents exposure of the operators to any hazardous process media as collection is always isolated from process and can’t be left open. From our sponsor Zedflo
Existing Process Sampling Methods and New Sampling devices for the Process Industry - Kevin Cook - Sampling is typically a major concern for most plants since product samples must be representative and accurate. Environmental and safety concerns related to sample taking of toxic or hazardous materials are also having a larger impact on the development of sampling devices - From our sponsor Tyco Flow Control Pacific.
