Column Specifications:

Low carbon C1 columns have been used for decades as alternative selectivity columns to the use of traditional C18s or when analyzing highly hydrophobic compounds that have too much retention on a C18 column. The weak attachment of a single carbon to the silica surface, has often been a weak point for these columns, making them vulnerable to degradation especially under acidic conditions, such as the use of TFA-containing mobile phases. Our Unison UK-C1 column was developed to address this weakness, utilizing ligand stabilizing techniques we developed in other columns such as the Scherzo or Intrada series. This proprietary process has resulted in the most stable C1 column on the market for use in acidic conditions.

• Amazing durability for acidic mobile conditions using formic acid or TFA
• Ideal for highly hydrophobic compounds that retain too strongly on C18s
• Allows uniform access to surface silanols for enhanced polar selectivity
• Alternative selectivity from traditional C18 columns
• Balanced mixture of polar and non-polar retention mechanisms

Unison UK-C1 Metal-free HPLC Columns

Improving peak shape for chelating or phosphoric compounds

2 mm I.D. - 30-250 mm Length - PEEK / SS316 - UHPLC compatible

• Metal-free (PEEK) internal structuren 
• UHPLC compatible metal housing
• Ideal for chelating compounds
• Ideal for phosphoric compounds
• LC-MS compatible 2mm I.D.
• Wide selection of stationary phases

This metal-free column is an Imtakt original design. The entire internal surface of these columns are made with PEEK material, including the frits, and is therefore extremely inert with respect to chelating compounds. The outer portion of these columns are made from stainless steel (SS316) making them suitable for extremely high pressures, and are UHPLC compatible. 

Phosphoric compounds can interact with the exposed metal surfaces within the column causing peak tailing, as seen in the figure to the left.

Imtakt's metal-free columns are designed to specifically improve these poor peak shapes by decreasing unwanted secondary chelating effects.

Improving peak shape of chelating or phosphoric compounds
Chelating and phosphoric compounds often have difficulty with poor peak shape and/or sensitivity due to undesired interaction between metal parts in the column and the structure of these compounds. Imtakt's UHPLC compatible metal-free columns, which are an Imtakt original design, will improve these
problems and are available in a wide range of stationary phases.
