Disclosed is a detector for chemical sensor devices, the detector being improved in detection sensitivity. Also disclosed is use of such a detector for chemical sensor devices. Specifically, disclosed is a detector for chemical sensor devices by which a substance to be measured is detected by adsorbing the substance contained in a medium on the surface thereof. The detector includes an adsorption layer containing hydroxyapatite or a substituted apatite obtained by substituting a part of elements in hydroxyapatite on a surface which is used for detecting the substance to be measured. Such a detector is greatly improved in detection sensitivity, and thus able to detect a very small amount of a chemical substance.

Detector for chemical sensor device and use thereof

A coal-methanol slurry having excellent storage stability, transportability and combustibility has been provided by using coal particles having a maximum particle size not greater than 1,500 .mu.m and a cumulative particle size distribution specified with respective to particles of 74 .mu.m and smaller, 10 .mu.m and smaller and 3 .mu.m and smaller and controlling the concentration of the coal particles within a specific range defined in relation to the degree of carbonization of the coal employed. A useful and advantageous production process of the slurry has also been provided, featuring an addition of water and the timing of its addition.
