摘要:
Method for detecting a basic target species in a fuel composition, involving (i) contacting the composition with a solid (for example paper) substrate carrying a spectroscopically active indicator which is capable of reacting with the target species, and (ii) detecting the spectroscopic response of the indicator on or following its contact with the fuel composition. The target species may be a detergent or dispersant additive or a constituent thereof, for example in an automotive fuel. The spectroscopic response may be a colour change, and the indicator may for example be a phenolphthalein indicator such as tetrabromophenolphthalein ethyl ester (HTBPE). Also provided is a test kit for use in the invented method, which may comprise a reference, such as a colour chart, with which to compare the spectroscopic response of the indicator. The indicator-carrying substrate is suitably packaged in a protective atmosphere.
摘要(中):
用于检测燃料组合物中的基本目标物种的方法,其包括(i)使所述组合物与携带能够与目标物质反应的光谱活性指示剂的固体(例如纸)底物接触,和(ii)检测光谱 指示器在与燃料组合物接触之后或之后的响应。 目标物质可以是洗涤剂或分散剂添加剂或其组分,例如在汽车燃料中。 光谱响应可以是颜色变化,并且指示剂可以是例如酚酞指示剂,例如四溴酚酞(HTBPE)。 还提供了用于本发明方法的测试套件,其可以包括用于比较指示器的光谱响应的参考,例如比色图。 指示剂携带衬底适当地包装在保护气氛中。
