Hi. Could u please explain how u can calibrate the Labomed Double beam UVD 32000. FOR G6P-DH .MEANS Where I can load my references sample . And after set wavelength. Which model should select from 1 to 3 in main screen
Sir you haven't uploaded the spectrophotometer part of the fluoride determination.. Can you please tell how much absorbance can occur for 1,2,3,4,5 ppm standard.. Are the absorbance fix or vary with the instruments
go to photometric mode . enter one cuvette in referance cell containing ref solution. and another cuvette containg standard 1ppm , take obsorbance meter will prompt you "do y want to enter more samples" than carry on with 2,3,4,5ppm and than sample n than blank.
@@sufiyaseen2294 I understand the operation of the instrument, but i want to know whether the absorbance for a particular concentration is specific in preparation of standard curve. Because we can't prepare the curve after trying 5) 6 days. Our curve come on fourth quadrant
Hi sir flouride test can we do in quatitation...uv 1900 spectrometer By keeping 0.5, 1,1.5, 2, 2.5ppm and then sample..it shows correct flouride in sample or no...t.@@sufiyaseen2294
Please share calibration of spectrophotometer by using k2cr2O7 and CuSO4 and analysis of Sulphate and nitrate in water sample

Very simply go to photometric measures set parameters, take absorbance and make calibration curve in excel and find out concentration

may vary slightly which depends on instrument accuracy and human error during standard preparation, environment factor etc.
