We are able to offer a variety of samplers. In order to ensure we provide you with the most suitable sampler for your application we suggest you go to the sampler comparison table which should help clarify the choices:

Laboratory costs for sample analysis are getting higher and hence it is all the more important that samples you obtain are an accurate and representative measure. Many factors need to be taken into consideration when designing a sampling program. Automatic samplers today also can offer sophisticated and flexible programs which can be adapted depending on the sampling objectives i.e:

• Time or flow proportional sampling
• Volume proportional sampling
• Parameter activated sampling
• Stormwater first flush sampling (pdf)

A detailed summary of factors to consider when designing a sampling program can be found in :

• Environmental sampling for trace analysis

Envitech can offer a complete installation service including the supply of sampler housings if required. Correct installation of both the sampler and the sample suction line and strainer are important to ensure a representative sample.

• Kiosk installations for portable / refrigerated samplers

Envitech can offer various options for transferring data generated from automatic samplers. Simple current loop and contact alarm outputs are available but in addition serial output and GSM remote modem access can also be provided:

• GSM modem / SMS text message alert with remote activation
• Hyperterminal link using modem / GSM

Envitech can provide a complete commissioning and training package with the supply of an autosampler. In addition some customers opt for Envitech to provide a maintenance contract which can be tailored to the customers requirements and the specific application. Remote GSM telemetry is also available for some samplers:

• Commissioning and training for automatic samplers
• Yearly / quarterly maintenance contracts

Health & safety issues are important considerations when dealing with analysis of contaminated samples such as waste water and process streams with sometimes unknown composition. Envitech has extensive experience of the handling samples from these type of applications and provides clear policy and procedures to minimise health and safety risks.

An overall Health & Safety policy can be supplied as well as specific information relevant to a specific sampling procedure.
