Note: Before using this test with your photometer for the first time, determine the reagent blank
value (see notes below).
YSI model no.: Al-1 TP
Category: RT (reagent test)
Cell: 28 mm
Measuring range: 0.002 - 0.250 mg/l Al
Pipette 20.0ml sample
into the empty cell. Add the contents of a
VARIO Aluminum
ECR F20 powder pack
and close the cell with
the screw cap. Dissolve the powder by
shaking. Allow to react for 30
seconds. Add the contents of a
VARIO Hexamine F20
powder pack and close
the cell with the screw
cap.
Dissolve the powder by
shaking. For reagent blank value
only:
Add 2 drops of VARIO
ECR-Masking RGT,
close the cell with the
screw cap and mix. Allow to react for 5
minutes. Insert the cell in the
photometer cell shaft
and start measurement.
Notes:
• To avoid errors due to contamination, rinse the equipment with hydrochloric acid solution (approx. 20%), then deionized
water beforehand.
• Adding the VARIO ECR-Masking RGT masking reagent is only required when determining the reagent blank value.
• The sample temperature has to be between 20 and 25 °C.
• We recommend to determine a new reagent blank value (deionized water instead of sample) for each test package started.
