Dilution Modules You may use a pump with a flow rate up to 50 cc min but be aware that there are certain limitations If your pump flow rate exceeds 5 cc min and your average dosimeter analysis produces nanogram levels of 75 or more it may be easy to collect enough mercury to saturate the 431 X sensor You thus risk over ranging your instrument and losing your collection data Higher flow rates may also impair the capture efficiency of the dosimeter We recommend that you drop your flow rate or use a dilution module AZI P N Z2600 3911 Lowering the flow rate to decrease the sample volume provides the greatest accuracy Using a dilution module introduces an additional 15 inaccuracy to your analysis As an alternative to the dilution module sample for shorter time periods Dilution Module Specifications Accuracy 15 of 10 1 ratio Low 0 7 mg m Hg Input concentration range High 5 0 mg ne He Housing Nylon Dimensions Il wx2 7 Ix3 h Weight 3 3 OZ The dilution module is factory set to a 10 1 ratio The mass of mercury entering the dilution module is reduced by 90 leaving a 10 X10 dilution concentration to be introduced into the Jerome 431 X Since this ratio can change slightly with use it is important to occasionally determine the current dilution module ratio to ensure accurate results For normal applications a X8 to X12 ratio is recommended The 431 X Functional Test Kit contains all accessories necessary to determine the cu
