Dionex ICS-2000 Reagent-Free Integrated Ion Chromatography System
The ICS-2000 system provides powerful analytical capabilities for isocratic or gradient separation of chromatographic analysis that offers superior sensitivity, accuracy, and dynamic range for many major anions and cations in a variety of sample matrices.The system features self generating eluent system, conductivity detector, AS40 Autosampler and Chromeleon software.
- Current Applications:
- Anion system is set up with an IonPac AS-18 column for analysis of F, Cl, NO3, SO4, Br, PO4, etc. Cation system is set up with an IonPac CS-12A column for analysis of Li, K, Na, Mg, Ca, NH4, etc.
- Potential Capabilities:
- Other ions and low MW organic molecules.
- Sample Types:
- Drinking water, snow, river and rainfall water, as well as other aqueous solutions containing particles not larger than 1-2 microns.
IC User Guidelines:
- The EAL offers both self-operation and sample drop-off analytical service for IC if they are natural water samples collected from river, lake, snow, etc. Click Here for current on-campus recharge rates.
- For drop-off service, please provide sample ID list with conductivity data. Click Here to download sample information sheet and IC drop-off service request form. The average turnover time is less than 2 weeks.
- If you select self-operation service, the EAL personnel will walk through with you from technical consultant, standard calibration preparation, instrument startup, and sample setup to sequence run as part of training section, and a minimum 3hrs technical support charge per operation will be billed except for instrument time. It generally needs two sections of such training, and for the third time operation, you will be on your own and only instrument time will be billed. Click here for technical support recharge rate.
- IC has quite high maintenance expenses including eluent cartridge, trap column, suppressor, analytical and guard columns, as well as periodic pump repair. The EAL covers all the above consumables if your samples do not require special column or suppressor. The EAL also provides calibration and instrument check standards if you don't plan run more than 500 samples or you need bring your own standard sets. However, users need to bring their own sample vials and caps or pay a nominal fee if using the EAL stock except drop-off service. It is charged 50 cents for one pair of sample vial and cap.
- All samples for IC analysis should be in aqueous form and must be free of solid particulates. Samples can be filtered through either a 0.45 or 0.2 um filter to remove any particles.
- You must sign up Logbook to record starting and ending time. Otherwise, a minimum of 24 hrs per day charge will be assessed.
- You can do data analysis after finishing running samples if nobody is using the system. Users are fully responsible for data analysis if self-operation service.
