LITHIUM BROMIDE SOLUTION ANALYSIS DATA

For proper performance and corrosion protection, the Lithium Bromide charge should be analyzed frequently.  Presented below is an example of a spreadsheet generated from a 12 month collection of analytical reports on a fictious sample.  Notice that no adjustment chemicals have been specified.  However, for an actual sample, the chemical recommendations to adjust the Lithium Bromide chemistry will be included.  The inhibitor analyzed for a specific sample varies depending upon the absorption chiller. 

To view this data in graphical form go to the ANALYSIS GRAPHS  page.  To learn more about the specific chemical components relating to Lithium Bromide chemistry go to the ANALYSIS INTERPRETATION page.
