Hai..for todays work, Im busy preparing standards for IC...previously only 2 points for standards (5,10,15ppm) but since i couldnt able to retrieve my thiosulphate reading, due to very low conc..
I added another 2 points for the calibration curve. Add up 0.1 and 1ppm...coz if not, rugi la data thiosulphate i, ada peak, but could not get the reading...quite lama skit hari ni...but luckily standards yg slalu wat hal, sumenya ok today...for standards 5,10 and 15ppm today, xde masalah..yang ada prob cume the added concentration...so wait n c lah ye...
