a-hex6
take about 10 mg of this product, weigh it accurately, put it in a 100ml measuring flask, dissolve it with acetone and dilute it to the scale, shake it well, take 2ml accurately and put it in a 50ml measuring flask, dilute with cyclohexane to the scale, shake well, take 5ml accurately, put it in a 100ml measuring flask, dilute with cyclohexane to the scale, shake well, as a test solution; in addition, take an appropriate amount of a-BHC standard, weigh it accurately, dissolve it with acetone and dilute it quantitatively to a solution containing about lug per lml, shake it well, and take an appropriate amount accurately, dilute quantitatively with cyclohexane to make a solution containing about 2ug per lml as a reference solution; Then take lml of the test solution, put it in a 10ml measuring flask, dilute it to the scale with the reference solution, and shake it well, as a system suitability solution. Measured by gas chromatography (General 0521). The capillary column with 5% phenyl-95% methyl polysiloxane as stationary liquid was used as the chromatographic column, the column temperature was 190°C, and the detector was electron capture detector. Take the applicable solution 1u1 of the system and inject it into human gas chromatograph to record the chromatogram. The number of theoretical plates shall not be less than 5000 based on the calculation of lindane peak, and the separation degree between lindane peak and a-BHC peak shall be greater than 3.0. The lul of the reference solution and the test solution were respectively injected into the gas chromatograph, and the chromatogram was recorded. If there are peaks in the chromatogram of the test solution that are consistent with the retention time of peak a-BHC, the peak area shall be calculated according to the external standard method, and the content of a-BHC should not exceed 1.0%.
acidity
take 10.0g of this product, add 25ml of acetone to dissolve, Add 75ml of water and 1 drop of Methyl red indicator solution, shake well, titrate with sodium hydroxide titration solution (0.02mol/L) until the solution is yellow, the results of the titration were corrected by a blank test. Consumption of sodium hydroxide titration solution (0.02mol/L) should not exceed 5.0.
