Abstract
Abstract An analytical element for quantitative analysis of bilirubin in a liquid sample by a diazo method, characterized in that a bilirubin detection reagent is a nondiffusive aryldiazonium salt having in the aryl group at least one substituent selected from the group consisting of an alkoxycarbonyl group, an alkylaminosulfonyl group and an alkylaminocarbonyl group.

Claim 1
Independent Claim
54 words
An analytical element for quantitative analysis of bilirubin in a liquid sample by a diazo method, characterized in that a bilirubin detection reagent is a nondiffusive aryldiazonium salt having in the aryl group at least one substituent selected from the group consisting of an alkoxycarbonyl group, an alkylam.inosulfo- nyl. group and an alkylaminocarbonyl group.
Claim 2
Dependent Claim
54 words
An analytical element for quantitative analysis of bilirubin in a liquid sample by a diazo method, characterized in that a bilirubin detection reagent is a nondiffusive aryldiazonium salt having in the aryl group at least one substituent selected from the group consisting of an alkoxycarbonyl group, an alkylam.inosulfo- nyl. group and an alkylaminocarbonyl group.
Claim 3
Dependent Claim
35 words
The analytical element claimed in claim 1, in which said aryl group of the aryldiazonium salt further contains at least one substituent selected from the group consisting of an alkyl group and an alkoxy group.
Claim 4
Dependent Claim
26 words
