TL;DR: In this article, an analyzer for carbon and sulfur content is described in which three glass electromagnetic valves are arranged between the sulfur determining eudiometer, and a liquid storing bottle; a carbon determining Eudiometer is in a cone funnel shape; a single wall glass in a lampshade shape is fixed on the core tube of the inner container of a double-layer absorption bottle; and the liquid difference method is adopted with two graduated rulers which can be proofread to each other.
Abstract: The utility model discloses an analyzer for carbon and sulfur content which is used to measure the carbon and sulfur content, comprising a sulfur determining absorption cup, and a sulfur determining eudiometer. The analyzer for carbon and sulfur content is characterized in that three glass electromagnetic valves are arranged between the sulfur determining eudiometer, and a liquid storing bottle; a carbon determining eudiometer is in a cone funnel shape; a single wall glass in a lampshade shape is fixed on the core tube of the inner container of a double-layer absorption bottle; 'atmospheric pressure process ', and 'liquid difference method ' which are adopted are provided with two graduated rulers which can be proofread to each other. The structures ensure the precision of measuring; the measuring time of the analyzer for carbon and sulfur content is half of the measuring time of the existing instrument. The analyzer for carbon and sulfur content which has simple operation and convenient operation is not influenced by altitude, zone, and environment.

TL;DR: In this article, the authors consider a volume of air trapped over a glycerol column in a eudiometer and demonstrate that there is an approximately linear relationship between the volume of trapped air and the height of the column.
Abstract: We consider a volume of air trapped over a glycerol column in a eudiometer. We demonstrate that there is an approximately linear relationship between the volume of trapped air and the height of the glycerol column. Simply by moving the eudiometer up and down, we cause the glycerol-column height and trapped-air volume to vary. The plot of volume versus height has a slope that depends on atmospheric pressure. We show how to determine atmospheric pressure from the plot of trapped-air volume versus glycerol-column height. This exercise allows students to use a familiar instrument in an unfamiliar way, while improving their understanding of pressure measurements and Boyle’s law.
