York Dairy Analyzer
The York Dairy Analyzer is a multi-component mid infrared
analyzer for dairy products. It measures the full set of
standard components following AOAC defined methods. Dairy
components measured include fat, protein, lactose, SNF and
total solids. Liquid samples of milk, cream, ice cream mix
and whey can be sampled.
Samples are
aspirated into the instrument through the front pipette. The
sample is homogenized and analyzed, with results displaying
on a linked PC display in less than one minute. Upon
measurement completion, a rinse is performed to remove the
sample from the analyzer.
Features and Benefits
Stable
Results
– Consistent daily measurements
provide the dependability needed for efficient laboratory
operations.
Test
time in less than 60 seconds
- Rapid analysis and low cost per test. Fast response to
products-in-process improves quality, standardization and
yields.
6-channel output including Fat C and Solids filters
- These filters, not provided in many other competitive
instruments, allow the York to accurately predict high fat
content in cream, and solids in sugar-added products. A
broader range of products can be tested.
AOAC
mid-infrared analysis method
- Reliable results and compatibility with the accepted AOAC
mid-infrared analysis method.
Unlimited
Calibrations – ProCal calibration software with
traditional bias and slope as well as multiple linear
regression is included in the software package.
Easy to
clean - A common cleaning detergent is all that is
required for daily maintenance. A more aggressive cleaner
can be utilized on a weekly basis.
Multiple
language readout and unit of measure options - Contact
the factory for details.
Automatic
Rinse and Zero Module – Improve productivity with the
optional module that provides automatic and programmable
cleaning and zeroing. This option eliminates the need for a
water bath and the independent presentation of rinse and
zero solutions to the pipette. Includes separate 5 liter
rinse and zero containers, valve manifold, peristaltic pump
and sample heater. Factory installed option only.
ProCal
Calibration Software
– Calibration is performed from the ProCal software included
as standard with every system. Create an unlimited number of
calibrations from results generated using the York analyzer
software. Standard MLR (Multiple Linear Regression) and
Slope and/or Bias correction options can be utilized by the
user.

Deviation) divided by average of reference results
multiplied by 100. Reference methods used are: Röse Gottlieb
for fat, Kjeldahl for protein, Polarimetry for lactose and
Drying Oven for total solids.
