Remote Access Sampler Systems (RAS)
McLane Remote Access Samplers are designed to collect in-situ water samples
in support of oceanographic research projects and environmental monitoring
programs. The RAS 3-48-100 and RAS 3-48-500 collect ambient water and
suspended material in tedlar bags, isolating the samples for subsequent
laboratory analysis. RAS systems can optionally be fitted with in-line
pre-filters. Each RAS can collect up to 48 samples, autonomously following
a user defined sampling schedule.
The McLane software provided with these systems makes them easy to use, yet
flexible and robust in support of your scientific goals. The operator has
control over sampling schedules, sample volumes, time limits, and other
sampling parameters. All versions of the RAS use the advanced control
algorithms developed for McLane pumps.
User manuals (listed below) include detailed photos, sample deployments and complete maintenance information.
Special Features:
RAS hardware and software can be customized to meet user needs. For
example, multiple intake RAS units can be used to acquire vertically
profiling samples across bottom boundary layers. The addition of external
sensors permits action triggered sampling.
We will work with you to develop a triggering algorithm based on a simple threshold mechanism, advanced time domain, frequency domain,
or statistical techniques. We have already developed many other options
and modifications and we are always ready to develop new features to meet
your needs.
A fully interactive deployment option is available for deployments equipped with a serial communication link. Sampling is triggered by a
remote user dynamically interpreting and responding to the changing conditions
at the site. Individual sample ports can be prepared in advance for
biological, chemical, or other types of samples and used as needed by the
investigators.
