implementation of FT-NIR instrument.
FT-NIR in the Dairy Industry
FT-Near-Infrared (FT-NIR) spectrometry and calibration are powerful tools for monitoring, regulating and
controlling processes that determine product quality within the dairy industry . It is possible to predict
chemical or physical characteristics of a milk sample, based on the comparison of its spectra to the spectra
of samples containing known characteristics.
Accuracy and Rapid Results
FT-NIR has been proven to provide accurate and rapid results and with little sample preparation and no
chemical usage. This makes FT- NIR suitable to be situated in the laboratory or near the production line thus
delivering the desire to improve efficiency in production.
Advantages
FT-NIR has advantages over other rapid instrumentation where samples do not require dilution, sample
preparation and usually FT-NIR instrumentation can accept any type of sample, whereas being liquid, powder

advantage over other rapid techniques is that once a calibration is carried out on a FT-NIR an instrument is
capable of operation over long periods of time with no further adjustments.

Sepacore
Sepacore prep. HPLC - High performance at low price
Buchi Sepacore® breaks up limits in preparative HPLC.
• Sublimation
If high back pressure makes a separation in flash
chromatography difficult, for example by running reversed
phase chromatography applications. Sepacore breaks up the
limits with its extended pressure range and guarantees a safe
and fast separation. Rapid, automated changes between
reversed phase and normal phase applications become
possible due to the ingenious software and high system
flexibility of Sepacore.
Transparent glass columns and hoses increase process safety
in preparative HPLC. Large columns with wide diameters make
it possible to clean up large sample amounts at high flow rates
and process costs are reduced as standard solvents can be used.
Its Sequential Module allows just that: a sequential run of up
to five pre-loaded cartridges or columns for high throughputs.

• Easy to use at highest flexibility for straight forward separations
• Transparent columns and hoses for a high process safety
• High sample quantities and flow rates for a speedy separation
• High performance at low price and low running costs
• Easy to separate complex sample mixtures due to a wide column range
• Sample amount of up to 100g
Biological Oxygen Demand – Cost Effective & Space Efficient
Memmert Peltier cooled incubators
• No compressor
• Energy saving
• Cost saving
• Space saving
• Noise free
• Maintenance free.
Incubation for 5 days at 20°C if you have a lot of specimens
is not convenient in a water bath. Utilising Peltier cooling
technology Memmert have incubators from 32 litres
to 750 litres – perfect for BOD testing
The Peltier technology does not utilise a compressor. This
is how the system can save up to 90% energy usage
compared to a compressor cooled incubator. This is a
huge cost saving over time.
Elimination of the cooling compressor while still maintaining
temperature below room temperature means there is no noise
or vibration with the added benefit of space saving.

Liquids in the one instrument
Answering the dairy requirement for a one instrument
solution.
A brief overlook at the calibrations Buchi have developed include:
· Milk (Whole, Skimmed, Pasteurized, Sterilized)
· Milk powders
· Serum and Ricotta Cheese
· Butter
· Yogurt and Kefir
· Cheeses (Fresh, Soft, Hard, Industrial)
