I. '\ ,J Bulletin No. &47· 1 March 1975 CALCULATIONS: (continued) WHERE Factor 0; Weight Reference Methazole x % Purity Reference Methazole Absorbance Reference Methazole Note 1: The weights given are for the specified 0.5 mm cell. For cells of other thickensses, adjustment of weights must be made to obtain an absorbance on the standard of about 0.2· 0.5 (30· 65% transmittance). Corresponding adjustments of sample weight should also be made. Note 2: Note 3: Chloroform solvent over acetone solvent for extracting is necessary due to the mode of treatment for impregnating the granulars as the fini~hed granular formula· tion. The PROBE is in a water hase matrix for application on the granulars. The amount of water present on the granulars is such that if acetone is used the amount ot water extracted with PROBE interferes in the IR .mea~~rement. Chloroform and water are immiscible. The dried sample must be free of residual CHC 13. Chloroform contamination will have ~n additive effect at the 755 cm -1 (13.25 microns) band. Chloroform has a strong absorption at this frequency. Extraction Procedure of Methazoh: from Solid PROBE Formulations USiflg a Soxhlet Extraction Apparatus and Appropriate. Extraction Solvent. General Procedure: Weigh sample into a single thickness extraction thimble (for wettable· powders line thimble with No.5 Whatman filter.paper) sealed in a capped weighing bottle to avoid solvent losses.-· l;xtract sample with approximately 150 ml appropriate extracting solvent in a Soxhlet ) , apparatus for 2 hours using a 250 ml round· bottom flask.

1. Sample weight is 11.0 ! 0.05 9 Chloroform (CHCI3) is the extracting solvent. Soxhlet extraction for 2 hours as outlined in General Procedure. (See/Note 2).
2. Strip CHCI3 under vacuum under moderate temperature (rotary evaporator) and dissolve the concentrate extract in 50 ml acetone using 50 ml pipet for delivery of solvent (See Note 3).
3. Scan the resulting solution in a 0.5 mm NaCI cell measuring the ausorbance at 755 em -1 (13.26 microns). ,., , Pagll 10 ;'. I ,. .. ~ ;) ~ - , " " -~-.--- " <.' Bull&tin No. 547·1 MIlCh 1876 U.PROBE 76% Wettable Powder Formulation
