i have been working as an analytical chemist in CHEMLOIDS
R&D centre in VIJAYAWADA for 4 1/2 years.I HVE AN EXP TO
HANDLING INSTRUMENTS LIKE HPLC ,UV, IR,ETC.THE PHENOMENON
OF ANALYSE SAMPLES PURITY & WHAT ARE THE OTHER IMPURITIES
IN THEIR USING SPECTROSCOPICAL INSTRUMENTS MAY CALLED
ANALYTICAL INSTRUMENTATION.TO MAINTAIN AN ANALYTICAL
INSTRUMENTS IS NOT EASY LIKE OTHER TECQNICS
TITRIMETRIC,GRAVIMETRIC .HERE MOST OF THE WORK RUNNIG BY
MANUAL.BUT WHERE AS IN INSTUMENTATION DEVISION WE CAN
CONTROL SYSTEMS BY GIVING SHEDULES TO SOME TIME EXTENT.HERE
WE HAVE TO USE ONLY HPLC GRADE SOLVENTS.OTHER WISE OUR
MIGHT DAMAGE.

hii, i'm had a sample of 1L that gone through extraction & evaporation. i used 0.5ml of methanol for reconstitution before injecting the sample to HPLC. i made a calibration curve using a standard solution but now i'm confused about how to display the concentration i got from the sample. for ex. i got 0.2ug/ml how i'm gonna explane this is for the 1L ? please help .. i'll really appreciate it thanks
