PURPOSE: To enable a content of methyl tertiary-butyl ether to be measured easily by allowing gasoline to flow to a glass tube where a light-development dye and a development substance are inserted for developing color and then comparing the color with a standard color. ;CONSTITUTION: Absorbent waddings 3, 5, and 7 as development substances are padded to portions A, C, and E of a specified glass tube 2 with a hole 1 at the bottom portion and aluminum oxide 4 and a color-development dye 6 are filled into the portions B and D by a specified amount. respectively. An organic solvent dissolution dy, etc., which are dissolved to methyl tertiary-butyl ether (MTBE) but are not dissolved to or solution retardant to gasoline and its contained constituents and then does not develop color nearly at all are used as the dye 6. the gasoline is allowed to flow to this glass tube by 1ml. A color of the dye 6 at the color-developed portion D and the color development at the portions A and B are compared with a standard color which is developed previously for each known content of MTBE by a same operation visually, thus enabling the MTBE content of gasoline to be measured simply.;COPYRIGHT: (C)1993,JPO&Japio
