Analytical Specialist

After 4 days of trying and trying to prove a limit test. Finally after tons of procedures, it worked!!I can't beilieve it despite the supplier's strange concentrations, despite the USP method,(didn't work with my supplier claim!)..when they all went wrong..I finally found a way to figured it out..when PhonolPhethalien became faint pink at 0.1 mL, gave me the biggest pleasure of the day!!It was an interesting investigation. My supervisor told me to be proud of myself!!seeing the damn pink colour;)Apparantly I am now an Analytical specialist in Qaulity Control! May be things are falling into the right position when you least expect it! just a wild thought. I hope it continue filling the voids!
