What is the sample injection technique for transformer oil samples?
This is extract from the Aquamax KF user manual; Program the Aquamax KF with parameters for the analysis. For Transformer Oil samples, these parameters are usually:- Result Format = mg/kg or ppm Calculation Mode = V/SG Sample Volume = 1.0 ml Sample SG = 0.875 ANALYSIS METHOD 1. Confirm that Aquamax KF is in “Ready” mode 2. Flush 1.0ml syringe several times (minimum 6 times) with sample 3. Fit luer needle and flush through with sample 4. Draw sample into syringe beyond the 1.0ml marking 5. Invert syringe so that any air bubbles can be ejected through the needle and adjust syringe plunger to the 1.0 ml mark 6. Wipe off excess sample from outside of needle using a clean, dry tissue or paper towel 7. Pierce needle through injection septa of titration vessel (1 – 2 cm) 8. Press START 9. Push needle into anode reagent and inject sample 10. Withdraw needle from titration vessel 11. Read result, in mg/kg (ppm) water, on display and printout 12.
