Richard Lab:IC eluents

System 1

Overview

IC System 1 consists of the ICEAS1 guard and analytical columns, a 750μL reaction coil, a UV detector (for organic acid detection), and an electrochemical detector with platinum electrode (for alcohol detection). The 4 eluent bottles are configured as listed here, with eluents A, B, and C requiring degassing: A = 100 mM methanesulfonic acid (2 L), B = 100 mM methanesulfonic acid (2 L), C = nanopure water (2 L), D = acetonitrile (1 L). Eluents A and B are used for running samples, while eluents C and D are available for system cleaning. A procedure for preparing eluents A and B is given below.

Materials

Supplies

• 2000-mL volumetric flask
• funnel
• eluent bottles
• 25 mL pipet
• vacuum pump
• 2000 mL vacuum flask
• stir plate and stir bar

Chemicals

• methanesulfonic acid (fume hood cabinet, acids)
• acetonitrile (fume hood cabinet, flammables)

Procedure

1. Step 1
2. Step 2
   • Step 2 has some additional information that goes with it. i.e. Keep at 4°C.
3. Step 3
   1. Step 3 has multiple sub-steps within it.
   2. Enumerate each of those.
