Dynamic Vapour Sorption
T
he development of D y namic
Vapour Sorption (DVS) by Professor Darryl Williams in 1994 revolutionised vapour sorption measurements.
The labour intensive desiccator test
was brought into the modern world
of isotherms and computerised data
capture and walk away operation. All
SMS models are developed, designed
and produced in house. The latest
DVS models include at the heart of
the system a new, purpose designed
T
he new Metrohm NIRS XDS
MasterLab Analyzer, designed by
FOSS and based on XDS near-infrared
(NIR) technology, provides the next
generation of dedicated NIR analysis
for the rapid non-destructive measurements of tablets, solids and liquids.
With the MasterLab Analyzer, one
can replace routine tests, reduce product
hold time and also virtually eliminate
quarantine time. The Analyzer supports
SMS UltraBalance, which replaces the
outdated Cahn technology.
DVS is now a valued tool in analytical laboratories all over the world.
Within research and development,
applications range from polymorphism
and stability studies to the studies of the
bulk and surface adsorption effects of
water, and organic vapours. It is also a
quality control analysis techniques for
both scale-up and production, and can
be found within the packaging area,
measuring both the efficacy and permeability of packaging materials, and the
effects of humidity and temperature on
the samples within the packaging. ?

uchi has launched their new
Dumas ana lyser Du Master
D-480. This makes them the only
provider of the three most widely used
key technologies for nitrogen and
protein determination, namely Kjeldahl,
Dumas and NIR. Whatever is required,
be it quality control for declaration
purposes, inspection of incoming or
outgoing goods, at-line production
control, the new Master series with the
KjelMaster K-375, DuMaster D-480
and NIRMaster Pro IP65 covers all
needs.

Buchi’s Triple Threat
B
Wirsam Scientific
ulabo’s FL range of Recirculating
Chillers offers an environmentally
friendly cooling system for routine
cooling applications in laboratories.
There are over 20 models, each with
temperature ranges from -20°C to
40°C. The temperature stability of the
PID control is ±0.5°C.
These models deliver up to 1.7kW
cooling capacity and can stand on or
under lab tables. The more powerful
models with up to 20kW of cooling
capacity are designed with small footprints. FL models are available with air
or water cooling.
Powerful pumps in the devices deliver
flow rates up to 60l/min with a pressure
of 6bars. All models from the 1bar pump
pressure have a
pressure indicator and a pump
pressure by pass
for the stepless
to consider in modern protein determination in food and feed, including
consistence and variation of the sample
matrix, random access vs batch processing, compliance with internal or official
regulations and versatile use for different
analyses. Buchi is a reliable partner who

adjustment of the pressure. All units
can be easily cleaned and are provided
with a splash- and waterproof keypad
with LED temperature indication. There
units also have a RS 232 interface.
To cool a standard rotary evaporator (1 to 3l) 200 days per year, about
250 000l of cooling water is needed.
This is equal to the water consumption
of a four-person household, however,
with an FL Cooler, this is reduced to
10l per year.
Not only does this series provide huge
water savings but it doubles condensation efficiency, which saves time. Up to
80% more solvent is recovered, which
also reduces the undesirable solvent
vapours in the lab. ?
