Which of the following statements is false? * O Chromatographic analysis is independent of film thickness Thick films are used with highly volatile analytes because such films retain solutes for a longer time, thus providing a greater time for separation to take place. Thin films are useful for separating species of low volatility in a reasonable length of time. Which of the following is true about a chromatogram? * The signal is plotted as a function of time or volume of the added mobile phase The position of the peak can be used to quantitatively identify the components of the sample The area under the peak provides qualitative measure of the amount of each component The following are characteristics of an ideal GC detector except-* O A temperature range from room temperature to at least 400°C. A long response time independent of flow rate. Adequate sensitivity

You are analyzing the effluent from a lotion plant for parabens using HPLC. You have a working standard solution with a concentration of 59.4 ppm which returned a Peak Height of 10,164 and Peak Area of 5,315.

Which is correct? Random errors affect accuracy and systematic errors affect precision. An accurate result shows agreement with the true or accepted value. Precise results can contain significant random error, but little systematic error. The standard deviation is a good measure of accuracy. Polydimethylsiloxane (PDMS) stationary phases have low polarities. Which of the following statements is TRUE about gas chromatography using PDMS stationary phases? The gas chromatography column is typically packed with silica microparticles. An oven is used to control the column temperature because a constant temperature is always needed in gas chromatography Octane (C8H18, boiling point: 126 ºC) is eluted later than dodecane (C12H26, boiling point: 216 ºC) 3-Pentanone ((C2H5)2CO, boiling point: 102 ºC) is eluted later than propanol (CH3CH2CH2OH, boiling point: 97 ºC)
