1 Put the C18 aside and take a look... 6 Reasons to try the EW Gemini

2 Reason #6 ALTERATE SELECTIVITY to your C18 Column Adding to your method development options, Gemini offers additional polar and aromatic selectivity, which may not be possible with a traditional C18 column. mau Gemini 5µm mau a 2b 3* 4 Gemini 5µm C18 3 2b 2a 4 APP ID APP ID min min * otice the improved resolution of closely eluting beta blockers with Gemini. Mobile Phase: 10mM Ammonium Bicarbonate, ph 10.5/Methanol (50:50) Flow Rate: 1.0mL/min Detection: 230nm Sample: 1. Atenolol 2. Labetolol (diastereomers) 3. Pindolol 4. Metoprolol

3 Reason #5 HYDROPHOBIC RETETIO similar to a C8 Reason #4 LOW BLEED Phenyl Phase To achieve dual selectivity (of both a phenyl phase and a short alkyl phase) Gemini uses a 6-carbon linker to attach the phenyl group to the silica surface. Compared to most other phenyl phases, which use a short 2 or 3 carbon linker, you will find this stationary phase a versatile tool for both your phenyl AD C8 methods. One of the weaknesses of traditional phenyl phases has been excessive bleed in UV and MS. Gemini demonstrates far lower bleed than many other phenyl columns. Indeed, in this example shows lower bleed than a popular C18 column.
