plz tall me that any pharmacopeia and guideline is par meted
to use 1.68,4.01,7.00,9.00,12.45 buffer for ph meter
calibration
Answer Posted / nagabhushan
We have to cover all regions like Acidic ,Basic and Nutrel medium in pH thatsy we use 1.68,4.01,7.00 ,9.0012.45 for 5 point calibration and there is another method for pH calibration that is 3 point calibration in this we use 4.00,7.00and9.20 buffers overall concept is to cover all regions in pH calibration
