five times greater than traditional radial
samplers, and the sampler itself can
be used indefinitely. These benefits
make large-scale air-monitoring studies
easier to run and more affordable.
Furthermore, the sampler's optimized
radius ratio ultimately reduces the
amount of adsorbent material required.
The POD sampler is compatible with
any commercial
thermal
desorption
system. - Markes International Ltd.,

Improve dosing accuracy and
safety for powder weighing
The XPR automatic balance (photo)
applies active machine learning to
powder weighing, delivering accuracy,
speed and safety for weighing
potentially toxic or active substances.
The XPR significantly reduces exposure
risk while ensuring precision and
safety by dosing from an enclosed
head into target vials or capsules
with openings as small as six millimeters
in diameter. It then uses live
feedback to learn a substance's flow
characteristics and improve dispensing
efficiency in real time. This can be
particularly effective when combined
with a sample changer that can process
as many as 30 samples in one
automated run. Spill risk is also eliminated,
as is the need to repeatedly
open the balance door and transfer
compounds from the main container
into a secondary container. The dimensions
of the balance mean that
it can be operated inside a glove box
or safety enclosure, further enhancing
containment. - Mettler Toledo,

A smart monitoring technology
for hydrocyclones
CycloneSense (photo, p. 24) is a smart
measurement system that provides
direct and continuous online monitoring
of a hydrocyclone air core, helping
to prevent common problems in
hydrocyclones, such as roping, while
increasing uptime. In grinding and floCO2
