Gas Chromatography: Purifying alcohol Introduction The goal of this lab is to understand the principles of chromatography by purifying alcohol using fractional distillation. Running standards with gas chromatography we were able to see and calibrate our data to find not only how much ethanol our alcohol attained but also what a mixed unknown sample contained. Chromatography is a way of being able to separate substances in solution that can help not only identify the analytes (the studied

Peroxidase Enzyme & Temperature Abstract: In this lab we tested the effect temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the different absorbance levels they produced every 20 seconds for two minutes straight using a spectrophotometer. The important part of this experiment was the temperature the enzyme concentration was made at. What we got from the experiment was at lower temperature we got very low numbers

Gas Tungsten Arc Welding The Process Gas Tungsten Arc Welding‚ also known as Tungsten Inert Gas Welding‚ is an arc welding process that uses a non-consumable tungsten electrode to produce a weld. The weld area is protected from atmospheric contamination by an inert shielding gas‚ such as argon or helium‚ and filler metal is normally used‚ except in autogenous welds. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and
