Communication & Your Career
This document discusses the importance of communication skills for careers and provides strategies for writing with readers in mind. It notes that writing at work differs from school in purpose, audience, and types. The main advice is to think constantly about readers by using a reader-centered writing process and talking with readers. Some strategies discussed are stating main points upfront, using headings and lists, explaining relevance, and writing in an easy to read style.
Gas Chromatography
Gas chromatography (GC) is a separation technique that uses a stationary phase coated on the inside of a column and a carrier gas as the mobile phase. The mixture of components is injected and separates into individual components as they travel through the column at different rates depending on their volatility and solubility. GC can be used to qualitatively and quantitatively analyze mixtures by measuring the retention times and peak sizes/areas of the separated components detected by the instrument. Key components of a GC system include the injector, column, detector, and recorder/integrator.
