writin again....
today, i specially dedicated my time just to wash all my apparatus after i got problem with my IC...dont know y but the water keep on dripping when it is not suppose to be...
have to contact the person in charge..ive tighten up the pressure valve but its not workin...
so proceed with something else...ive to wash all my apparatus after my pre-liminary once again failed!
what else to SAY???? grrrrr....still couldnt figure whats wrong...
so far, the conc of sulphate is not even decrease which means that probably there is a leak in the tubing area or possibly coz of the valve...i dont know...
need to RE-DO again n again!!!!!
above: pictures of bottles...nearly hundreds of them...soaked with dettol 1st for a few hours n then only with 15% of nitric acid overnite just to get rid of any possible contaminants..
thats how it works to prevent any contamination...so tomorrow will continue rinsing it with tap water n ultra pure water twice before leaving it in the oven for about 65 degree C. then only i can say that all my apparatus are clean n can be use...
