Laboratory sample of a deposit anlaysis prior to
application recommendations:

Inorganic Analysis
Visual Observation:
The deposit sample appears as a reddish/brown scale deposit.
Sample ID: A. Deposit from Steam Boiler "WWA-3" 
 
The sample was dried and ashed. Consequently, the elements were converted
to the oxide form. Chemical analysis of the ash indicated the presence of the
following (expressed as a percentage of ash):

Date Sample Obtained:  1/10/16

Carbonate Spot Test                            Negative
Loss on Ignition (@875 Deg. C)a         10.8%
Ash Content (@875 Deg. C)a                89.2%
Calcium (as CaO)                                  31.5%
Phosphorus (as P2O5)                         22.2%
Magnesium (as MgO)                            16.4%
Sulfur (as SO3)                                    LT 1.3%
Iron (as Fe2O3)                                     5.1%
Sodium (as Na2O)                                 2.8%
Silicon (as SiO2)                                   19.1%
Potassium (as K2O)                             LT 1.2%
Aluminum (as Al2O3)                            0.8%
