Do you use Ion Chromatography?

Why Should You Attend:

Ions are dissolved, electrically charged chemical species. They fall within one or another of two categories, cations or positively-charged ions and anions or negatively-charged ions. Many ions are quite common or quite important. For example, water salinity is determined by the dissolved amount of salt in the sample. Salt dissolves to form the positive sodium cation and the negative chloride anion. Another example is the carcinogenic chromium (VI) ions, most typically the anions chromate and dichromate. Other forms of chromium are not carcinogen and of no health concern, but can interfere in a determination for chromium (VI). A method such as ion chromatography can determine chromium (VI) levels without these interferences. This webinar will cover separating ions in an analysis that can differentiate various ions from each other.

Analysis of ions by ion chromatography can be a challenged that depends on which ions must be looked for and what level of detection must be seen for each. Additionally, the sample type, the matrix, can greatly affect the analysis. This webinar will describe the various types of ion chromatography, their strengths and weaknesses, their applications.

Areas Covered in the Webinar:

• Ion exchange
• The mechanism of ion exchange
• Bionic charge and softness/ hardness
• Ion suppression
• The approaches to ion suppression
• Chemical removal/ neutralization
• Mechanical removal (membranes, etc.)
• Ion pairing and micelle chromatography
• What ion pairing does
• What micelles are and how they can separate
• Hydrophilic Interaction Chromatography (HILIC) and aqueous normal-phase chromatography
• Chelation chromatography and other specialty columns

Who Will Benefit:

This webinar will provide valuable assistance to all personnel working in a GLP certified laboratory and for those performing waste and treated water analysis and ion analysis for biomedical work. Employees who will benefit include:

• QA Managers
• QC Managers
• Analytical Chemists
• Validation Specialists
• Laboratory Managers and Supervisors
• Regulatory Affairs Personnel
