The present invention relates to an enzyme electrode including: a carbon particle; a metal particle held on the carbon particle, the metal particle having a catalytic activity against a redox reaction; a redox enzyme. The enzyme electrode of the present invention further includes a high-resistance particle enhancing an electrical resistance, the high-resistance particle being chemically stable. The high-resistance particle contains an inorganic substance, for example. The inorganic substance is aluminum oxide or smectite, for example.

Enzyme electrode

A pelletfor use in spectrometry includes a first powderof a light transmitting material in a compression-molded form, and a second powderwhich is hydrophilic and water-insoluble and is dispersedly mixed in the first powder. A sampleto be subjected to spectrometry is e.g. in a powdery form and dispersedly mixed in the first and the second powdersand. When the sampleis a hydrate, the second powderexerts the effect of accelerating dehydration of the sample, so that stable spectrum data on the sample in the dehydrated state is obtained early. This makes it possible to perform a processing such as identification of the sampleearly and precisely.
