Liquid Chromatography – Laboratory #18 Introduction: We are using liquid chromatography to separate the colored substances in grape-flavored drinks. We separate the component dyes‚ and then we separate the flavorings and citric acids. Background: Chromatography is a process that is used to separate a substance into its component parts. The separation occurs between the stationary and moving phase of the lab. The moving phase consists of a fluid and the stationary phase consists of a solid

Lab Report 1: Measurement Lab Date: January 17‚20XX Lab Partners: XZ Report Date: January 24‚2014 Report Written by: XXXXXX Introduction: Measurement is a form of quantitative observation. The ability to make accurate and precise quantitative observations is crucial to science. Accuracy in this sense refers to the closeness of the measured result to the hypothetical “true” value (Motzny 2014). Having a precise measurement implies its exactness.
