Water quality testing products for beer analysis and production applications
Rapid test analysis of VDK and bitterness
according to MEBAK standards
Malt analysis, decarbonisation and
turbidity analysis using filter paper
Rapid testing of sterilised water
HPLC and GC analysis of hops and pesticides
Beer analysis according to MEBAK standards
The Central European Board for Brewing
Analysis (MEBAK) has developed harmonised standards for the analysis of raw
materials, auxiliary materials and consumables. With the NANOCOLOR UV/VIS II
you can easily and reliably analyse all photometrically evaluable parameters,
such as.
●Diacetyl analysis by the EBC method
●Colour of beer
●Bitterness
●Butanedione (VDK)
●Ph, trace iodine
●Free Amino Nitrogen (FAN)
●Other parameters
New reagents for testing VDK and bitterness
The new reagent can be used for VDK
(985010) and Bitterness (918172) testing. With the NANOCOLOR Bitterness Reagent
(918172), bitter substances (mainly iso-alpha-acids) in beer are extracted from
beer samples using iso-octane and then measured in the 275 nm UV range using a
10 mm quartz test tube.
VDK can be determined quickly and easily
using the NANOCOLOR preloaded tube reagent (985010).Butanedione reacts with
phenylenediamine derivatives to form quinoline derivatives, which are
determined photometrically using a wavelength of 335 nm.
For the determination of o-phenylenedione according to MEBAK or for the determination of o-phenylenedione with NANOCOLOR pre-filled tube reagents, steam distillation must be used to prepare the sample solution. We have compiled the test setup and the required materials in a customer information brochure.
Filter paper for brewery laboratories
MACHEREY-NAGEL has 111 years of experience
in the production of high-quality filter papers.
Breweries have a wide range of requirements
for filter paper, and different grades of filter paper differ in parameters
such as retention capacity, filtration speed and grammage. Therefore, breweries
use a wide range of different filter papers.
Depending on the application,
MACHEREY-NAGEL always offers the most suitable filter paper.
● Folded filter papers for rapid
decarburisation of beer. (MN 616, MN 514, MN 520)
Nitrogen-free filter papers for malt
analysis (MN 614)
● Thicker (MN 616) or diatomaceous earth
coated papers (MN 660), as well as filter films for clarifying clear yeast
samples.
Test strips for rapid analysis on site
QUANTOFIX test strips are suitable for
quick tests on production sites. They are often used to check whether a
parameter exceeds a limit value, e.g. chlorine dioxide at a dosing station.
Test strips are also suitable for the detection of disinfectant residues in
rinse water, as well as for quick and easy control of parameters in production
that cannot be distinguished by the senses. For example, sugar-free soft drinks
can be reliably distinguished from sugary soft drinks.
With our test strips, the following
parameters can be detected.
● Residual chlorine
●Peroxides
●Peroxyacetic acid
●Chlorine dioxide
●Glucose
●Ascorbic acid (vitamin C)
Brewery Wastewater Testing
The NANOCOLOR range of analytical products
provides fast and reliable analysis of brewery wastewater. In addition, the
products are also suitable for the operational analysis of wastewater treatment
plants. In particular, MACHEREY-NAGEL has seven iso-compliant reagents for COD
analysis in its portfolio. In addition the reagents for ammonia, nitrate and
total nitrogen are also iso-compliant.
The NANOCOLOR range of analytical products
is particularly easy to use and is therefore the preferred choice for routine
analysis, self-monitoring and analysis of brewery wastewater.
●Easy-to-operate photometer
●Heater for rapid sample digestion
●Easy-to-use pre-filled tube reagents
●Reliable analytical quality assurance

Innovative spectrophotometers
To ensure consistently good quality, raw
materials, products and processes, as well as waste water, all need to be
analysed as part of quality control. With the NANOCOLOR VIS II
spectrophotometer, MACHEREY-NAGEL provides every brewery with an instrument for
all stages of the brewing process as well as for the complete analysis of the
product.
● Colour touch screen for a revolutionary
user experience
●Intuitive graphical menu navigation
●Turbidity interference monitoring (NTU
CHEKC)
●Proven interface options
●Easy data transfer to Microsoft Excel,
LIMS or ACRON
