Exchange Chromatography Week 10 TAG Question 1: Chapter 6-4 of your technique book provides a detailed description of how to run a ion- exchange column. Assume you have a cation-exchange column already prepared and ready to use. Create an outline of no more than 10 steps describing how you will regenerate the column‚ load your sample and collect the hydronium ion released. 1. Open the stopcock at the bottom of the column and allow solution to drain out until the solution level in the column is

EXECUTIVE SUMMARY: The main objective of this project was to carry out a design on the Propane distillation column for a process that produces 1‚3 Butadiene. The raw materials used are Butane‚ Oxygen and Water and the process capacity is 100 000 tonnes per annum nominal. In the previous work it was stated that the plant is located in China. The main location of the plant is in the capital city of the Gansu Provence‚ Lanzhou. This was decided as the location over other provinces due to the excellent

I. Column Oriented Database A column-oriented DBMS is a database management system (DBMS) that stores data tables as sections of columns of data rather than as rows of data. In comparison‚ most relational DBMSs store data in rows. This column-oriented DBMS has advantages for data warehouses‚ customer relationship management (CRM) systems‚ and library card catalogs‚ and other ad hoc inquiry systems where aggregates are computed over large numbers of similar data items. It is possible to achieve
