    • A method for rapidly detecting the presence of formaldehyde in a urine sample (e.g., urine or a urinary material associated therewith, such as headspace gas located associated with urine) is provided. The method includes contacting the urine sample with a substrate on which is disposed a colorant that is capable of undergoing a detectable color change in the presence of formaldehyde. Without intending to be limited by theory, it is believed that oxidation of the colorant by formaldehyde induces either a shift of the absorption maxima towards the red end of the spectrum ("bathochromic shift") or towards the blue end of the spectrum ("hypsochromic shift"). The absorption shift provides a color difference that is detectable, either visually or through instrumentation, to indicate the presence of formaldehyde within the urine sample. For example, prior to contact with a urine sample, the colorant may be colorless or it may possess a certain color. However, after contacting the urine sample and reacting with formaldehyde, the colorant exhibits a color that is different than its initial color. The color change may thus be readily correlated to the presence of formaldehyde in the urine sample.
    • 提供了一种用于快速检测尿液样品中甲醛存在的方法(例如,尿液或与其相关的尿液,如与尿液相关联的顶部空间气体)。 该方法包括使尿样与底物接触,其上设置有能够在甲醛存在下经历可检测的颜色变化的着色剂。 不期望受理论的限制,据信甲醛对着色剂的氧化会诱发吸收最大值朝向光谱红色端(“红移”)或朝向光谱蓝色端(“变色” 转移”)。 吸收移位提供了色彩差异,可以在视觉上或通过仪器检测来显示尿液样品中甲醛的存在。 例如,在与尿样接触之前,着色剂可以是无色的或可以具有一定的颜色。 然而,在接触尿液样品并与甲醛反应之后,着色剂显示与其初始颜色不同的颜色。 因此,颜色变化可能容易地与尿液样品中甲醛的存在相关。
