Both, taste and shelf life of the product are affected by the amount of CO2 dissolved in the product.
A
reliable measuring method is the basis for maintaining a uniform carbon
dioxide content in beer, carbonated water and soft drinks. The demand
for an accurate and user independent CO2-measurement device led to the
development of the automatic Steinfurth CO2 tester CO2MS.
The
Steinfurth System offers very quick return of investment combining
automatic functioning with integrated sample preparation and easy
operation. The instrument can be operated in laboratory or outsourced to
the filling line (with the possibility for optional extension to the
modular Steinfurth CPA - Compact Package Analyzer).
The CO2MS is the perfect tool for high efficient QC in modern bottling facilities.
Based
on the laws of Henry and Dalton, the concentration of CO2 dissolved in a
liquid can be determined in a closed package by measuring the pressure
and temperature when a state of equilibrium between the gas and the
liquid phase exits.
The CO2MS accurately computes the CO2 by using these measurements in conjunction with the particular product CO2-formula.
A
state of equilibrium is achieved in our process by evenly rotating the
bottle in a vertical orientation for a short period of time prior to
performing the measurement. The overhead tumbling of the beverage
packages provides an optimal equilibrium phase for accurate calculations
of the CO2 content.
The Steinfurth CO2MS device combines the perfect sample preparation with accurate measurement.
The CO2MS-2
fitted with a high precision digital manometer, displays the
equilibrium pressure at the end of the shaking process. The temperature
needs to be measured with a thermometer and the carbon dioxide content
read off a CO2-chart, or calculated manually.
