Overview

The COSMOSIL 5C18-MS-II chromatographic column is one of the most balanced and basic performance columns in the COSMOSIL series (with fast peaks, sharp peak shapes, and high theoretical plate numbers for separating alkaline compounds and metal coordination compounds). Its quality is stable and reliable, with rich analysis data and simple analysis condition settings, making it the preferred choice for reverse phase columns.

reproducibility

If an insufficiently capped C18 chromatographic column is used to analyze alkaline compounds, you will spend a lot of time adjusting the mobile phase. You may need to:

Three or more organic phases and buffer salts

Ionic reagents or additives

Buffer salts with different pH values

In addition, complex flow is a test of relative reproducibility.
Due to the use of a new capping technology, COSMOSIL 3C-18 only requires a simple mobile phase to achieve excellent peak shapes and separation.

Usage information

chromatographic column	3μm 3C₁₈-EB
Inner diameter (mm)	1.0	2.0	3.0	4.6
Column length (mm)	ALL	ALL	ALL	10	50-250
Factory solvent	Acetonitrile/water=60/40
flushing method	Method for removing buffer, salt, and acid from the chromatographic column: Rinse with a mobile phase free of buffer, salt, and acid for 10-15 minutes. Example: When the mobile phase is methanol/phosphate buffer (20mmol/L)=50/50, rinse with methanol/water=50/50 The method of flushing the attached substances in the chromatographic column and the solution when the baseline is unstable When the sample is not protein, rinse with methanol or *. When the sample is protein, use 0.1%C2HF3O2Rinse with 50-70% acetonitrile/water
