38、p:/www.ansi.org.1*A Summary of Changes section appears at the end of this standard.5.1.1.2 CondenserA condenser in the form of a metal coilapproximately 25 mm in diameter and 50 mm in lengthattached to, and with the ends projecting through, a lid ofsufficient diameter to cover the neck of the flask

39、as shown inFig. 1. The coil shall be made from stainless steel, tin,tin-plated copper, or tin-plated brass tubing having an outsidediameter of 5 to 8 mm and a wall thickness of 1.5 mm. Ifconstructed of tin-plated copper or brass, the tin coating shallhave a minimum thickness of 0.075 mm. The exposed

40、 surfaceof the coil for cooling purposes is about 115 cm2.NOTE 2The use of a water flowmeter/controller unit that monitorswater flow to the condenser that shuts off the heat source when the flowrate drops below a pre-set limit has been found suitable to preventvaporized toluene from igniting. The us

41、e of such a device is recom-mended.5.1.1.3 Extraction Thimble5The extraction thimble shallbe of a refractory porous material, pore size 20.0 to 30.0 m (ascertified by the manufacturer), 25 mm in diameter by 70 mm inheight, weighing not less than 15 g and not more than 17 g.Suspend the thimble from t

42、he condenser coil by means of abasket so that it hangs approximately midway between thesurface of the extracting solvent and the bottom of thecondenser coil.5.1.1.4 Thimble BasketThe thimble basket shall becorrosion-resistant and shall be made of platinum, stainlesssteel, nickel-chromium alloy, or s

43、imilar material. Fig. 2 showsthe design and dimensions of two typical baskets that havebeen used successfully in the industry.5.1.1.5 Water CupUse a water cup when testing a sampledetermined to have a water content greater than 10 % volume(see Fig. 1, Apparatus B). The cup shall be made of glass,con

44、ical in shape, approximately 20 mm in diameter and 25 mmdeep, and have a capacity of approximately 3 mL.Aglass hookfused on the rim at one side is so shaped that when hung on thecondenser the cup hangs with its rim reasonably level. In thisprocedure, suspend the thimble basket as shown in Fig. 1,App

45、aratus A by means of the corrosion-resistant wire loopedover the bottom of the condenser coil and attached to the basketsupports, or as in Fig. 1, Apparatus B, where the wire supportsof the basket are attached to hooks soldered to the underside ofthe condenser lid.5.1.1.6 Source of HeatUse a source

46、of heat, preferably ahot plate operated under a ventilated hood, suitable for vapor-izing toluene (WarningFlammable.)5.2 Analytical BalanceUse an analytical balance, with anaccuracy of 0.1 mg. Verify the balance, at least annually,against weights traceable to a national standards body such asthe Nat
