Refer to following recommendations to select an appropriate mobile phase condition. (1) The effect of organic solvent type and content In general, acetonitrile/water is used as mobile phase. Retention increases as water content in the mobile phase decreased. (Fig.1) Use acetonitrile content in the mobile phase within the range of 0-95% (in general 50-95%). Methanol/water generates shorter retention than acetonitrile/water. (Fig.2) Use only HPLC grade solvent 8 meso-Erythritol Tris(hydroxymethyl) Aminomethane Guanidoacetic Acid 4 meso-Erythritol 7 Leucine 6 k' 8 Leucine 6 Tris(hydroxymethyl) Aminomethane 5 k' • • • • • 4 3 2 2 1 0 65 70 75 80 85 90 95 100 0 Acetonitorile Acetonitrile content(%) Methanol Fig.1 The effect of acetonitrile content on retention Fig.2 Difference of acetonitrile and methanol on retention Column; COSMOSIL HILIC Mobile phase; Acetonitrile/ 10mmol/l CH3COONH4 Column; COSMOSIL HILIC Mobile phase; Organic solvent/ 10mmol/l CH3COONH4 = 90/10 (2) The effect of buffer pH • Keep pH of the mobile phase within the range of 2-7.5. • The buffer around neutrality generates larger retention. (Fig.3) 4.5 meso-Erythritol 4 Leucine 3.5 Tris(hydroxymethyl) Aminomethane Guanidoacetic Acid k' 3 2.5 2 1.5 1 Fig.3 The effect of buffer pH on retention 0.5 0 2 3 4 5 6 7 8 9 Column; COSMOSIL HILIC Mobile phase; Acetonitrile / 10mmol/l buffer = 90/10 pH (3) The effect of salt type and concentration • When analyze ionic compounds, add salts or buffers in the mobile phase. • When mobile phase has high acetonitrile content, note dissolubility of the salt. The dissolubility of phosphate buffers used widely in reversed phase chromatography is low in acetonitrile. Therefore use of phosphate buffers is not recommended. Keep the concentration of acetonitrile under 70% if use a phosphate buffer. Check that the salt does not precipitate when mixed with acetonitril before use. • Ammonium acetate or formic acid ammonium buffers are recommended because they are soluble in high acetonitrile content. • Use the buffer concentration within the range of 5 - 100mmol/l. Moreover, check that the salt does not precipitate after mixing buffer and acetonitrile. • High salt concentration inhibits ion exchange capability and decreases retention. (Fig.4) • Run mobile phase through membrane ¿lter (less than 0.45ȝm in pore size) before use. 10 Benzoic Acid 8 k' 6 4 2 0 Fig.4 The effect of salt concentration on retention 0 25 50 75 Buffrer Concentration(mmol/l) 6 100 Column; COSMOSIL HILIC Mobile phase; Acetonitrile / 10mmol/l CH3COONH4 = 50/50 (4) Selection of mobile phase Following are the recommended mobile phases for different compound types. → Acetonitrile / Water = 90/10 → Acetonitrile / 10mmol/l CH3COONH4 = 90/10 → Acetonitrile / 10mmol/l CH3COONH4 = 70/30 → Acetonitrile / 10mmol/l CH3COONH4 = 50/50 Neutral compounds Basic compounds Amphoteric compounds Acidic compounds ↓ not eluted Acetonitrile / 10mmol/l Phosphate buffer (pH7.0)= 50/50 (5) Two interactions (hydrophilic interaction and anion exchange capability) The retention mechanism of COSMOSIL HILIC is the combination of hydrophilic interaction and anion-exchange, and the retention can be controlled by changing the mobile phase. More speci¿cally, the hydrophilic interaction can be enhanced by increasing the organic solvent concentration while suppressing the ionic interaction with high salt concentration.

The peak shape might improve. • Add 5mmol/l EDTA to mobile phase. • Change to citrate buffer.

Air bubbles generate detection noise and accelerate column deterioration. • We recommend keeping the chromatography conditions constant, since frequent changes of mobile phase shorten column life. 7 8 9 10 COSMOSIL Applications COSMOSIL Application has more than 7,000 applications using COSMOSIL columns.
