WHAT IS GSM AND HOW TO CALCULATE




          WHAT IS GSM AND HOW TO CALCULATE

GSM MEANS
GSM is an acronym standing for 'Grams per Square Meter'. Quite simply, it allows buyers and  suppliers to know exactly about the quality of paper or foil that is being ordered.
AND HOW TO CALCULATE GSM OF PAPER AND FOIL
IT’S VERY SIMPLE, FIRST WE CUT OF RECTANGULAR PIECE OF PAPER AND FOIL
IN ANY SIZE ACCORDING TO YOUR CHOICE.
MEASURE THE DIMENSIONS OF RECTANGULAR PIECE IN MILIMETER (mm) OR CENTIMETER(cm)
SUPPOSE THE DIMENSIONS OF RECTANGULAR PIECE IN CENTIMETER (cm)
ONE METER IS EQUIVALENT TO 100cm
ONE SQUARE METER = 1meter x1meter
                                      = 100cm x 100cm
                                      = 10000cm2
LENGTH: 7.0cm
WIDTH  :  3.0cm
WEIGHT:  0.8 g
FORMULA :    WEIGHT OF PIECE OF PAPER OR FOIL (g) x 100 x 100
                                               LENGTH(cm) x WIDTH (cm) 

                     =     0.8 x 10000
                              7.0 x 3.0
                     =     380.95    
                     =     THE GSM IS 380.95 g PER SQUARE METER

SUPPOSE THE DIMENSIONS OF RECTANGULAR PIECE IN MILIMETER (mm)
ONE METER IS EQUIVALENT TO 1000mm
ONE SQUARE METER = 1meter x1meter
                                      = 1000mm x 1000mm
                                      = 1000000mm2
LENGTH: 70.0mm
WIDTH  :  30.0mm
WEIGHT:  0.8 g
FORMULA :  WEIGHT OF PIECE OF PAPER OR FOIL (g) x 1000 x 1000
                                            LENGTH(mm) x WIDTH (mm) 

                     =     0.8 x 1000000
                              70.0 x 30.0
                     =     380.95    
                     =     THE GSM IS 380.95 g PER SQUARE METER

Difference Between μg ,mcg or ppm

Difference Between μg  ,mcg or ppm All are same, why we can say all are same Tri to understand as following μg    =   one millionth ( 1×10 −6 ) of a   gram ,        = one gram/1000000 = 0.000001g or 0.001mg mcg =   one millionth ( 1×10 −6 ) of a   gram        = one gram/1000000 = 0.000001g or 0.001mg ppm =   ppm   (parts-per-million)            one millionth ( 1×10 −6 ) of a   gram .         =one gram/1000000 = 0.000001g. or 0.001mg So, we can say that the μg  ,mcg or ppm are same. For example : We want to make 100ml of 10 μg/ml dilution.            = 10 x 0.000001g( μg )= 0.00001g/ml or 0.01mg/ml.               For 100ml = 0.01mg x 100ml or...

METHOD OF ANALYSIS OF TOLNAFTATE

METHOD OF ANALYSIS OF TOLNAFTATE Weight accurately about 0.4 g of Tolnaftate, dissolve in 50 ml of anhydrous glacial acetic acid . Previously neutralized with 0.1 M Perchloric acid . Using Crystal Violet as indicator and add 20 ml mercuric acetate solution ( Previously neutralized with 0.1 M Perchloric acid . Using Crystal Violet as indicator) Titrate with 0.1 M Perchloric acid upto green colour changed. Each ml of 0.1 M Perchloric acid is equivalent to 0.030741g of Tolnaftate .
