HPLC Method for Analysis of Inorganic anions on BIST™A+ Column

| High Performance Liquid Chromatography (HPLC) Method for Analysis of Inorganic anions, Chloride, Bromide, Nitrate, Iodide, Perchlorate
Using SIELC’s newly introduced BIST™ method, a mixture of many different inorganic anions can be separated on a negatively-charged, cation-exchange BIST™ A column, contrary to conventional chromatographic wisdom. There are two keys to this retention method: 1) a multi-charged, positive buffer, such as N,N,N’,N’-Tetramethyl-1,3-propanediamine (TMDAP), which acts as a bridge, linking the negatively-charged anion analytes to the negatively-charged column surface and 2) a mobile phase consisting mostly of organic solvent (such as MeCN) to minimize the formation of a solvation layer around the charged analytes. Other positively-charged buffers that can generate BIST™ include Calcium acetate and Magnesium acetate. Using this new and unique analysis method, these anions can be separated, retained, and detected through ELSD. This method is also compatible with Mass Spectrometry. |

Application Column
BIST A
BIST™ columns offer a unique and effective way to achieve separations that were traditionally challenging or even impossible with other HPLC columns. With the use of a special mobile phase, these ion exchange columns provide very strong retention for analytes with the same charge polarity as the stationary phase, unlocking new chromatography applications. What makes BIST™ columns stand out is their proprietary surface chemistry, which results in superior selectivity, resolution, and sensitivity. These columns offer a simple, efficient solution for a variety of analytical challenges, making them an excellent choice for researchers and analysts across many different fields.

HPLC Method for Analysis of Sulfonic acids on BIST A+ Column by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Sulfonic acid
Methanesulfonic acid is a popular non-volatile catalyst used in organic reactions due to it being a strong acid. Other sulfonic acids, like 1-Pentanesulfonic acid, 1-Heptanesulfonic acid, 1-Decanesulfonic acid, and 1=Dodecanesulfonic acid are typically used in ion chromatography and for organic syntheses. Using SIELC’s newly introduced BIST™ method, a mixture of these Sulfonic acids can be separated on a negatively-charged, cation-exchange BIST™ A+ column, contrary to conventional chromatographic wisdom. There are two keys to this retention method: 1) a multi-charged, positive buffer, such as N,N,N’,N’-Tetramethyl-1,3-propanediamine (TMDAP), which acts as a bridge, linking the negatively-charged anion analytes to the negatively-charged column surface and 2) a mobile phase consisting mostly of organic solvent (such as MeCN) to minimize the formation of a solvation layer around the charged analytes. Other positively-charged buffers that can generate BIST™ include Calcium acetate and Magnesium acetate. Using this new and unique analysis method, these Sulfonic acids can be separated, retained, and detected through ELSD. This method is also compatible with Mass Spectrometry (LC-MS) and CAD.

HPLC Separation of Potassium, Perchlorate, Methanesulfonic, Chloride, Bromide, and Nitrate Ions on Obelisc N
March 3, 2010
Ion chromatography is usually used for analysis of hydrophilic organic and inorganic ions. Same separation can be achieved on HILIC/mixed-mode Obelisc N HPLC columns. Obelisc N HPLC columns have very polar groups on their surface: one of the groups is basic and the other acidic. In case of low organic concentration, two groups are connected by hydrophilic linker. Obelisc N column can be used as cation-exchange and anion-exchange column. This allows to separate positively and negatively charged molecules in one run. Five anions (chloride, bromide, methanesulfonate, nitrate and perchlorate) along with one cation (sodium) were separated in one run. Method is compatible with ELSD, CAD and LC/MS and can be used for analysis of various hydrophilic and hydrophobic cations and anions in one HPLC run.

| Buffer | AmFm |
| Flow Rate | 1.0 ml/min |

Application Column
Obelisc N
SIELC has developed the Obelisc™ columns, which are mixed-mode and utilize Liquid Separation Cell technology (LiSC™). These cost-effective columns are the first of their kind to be commercially available and can replace multiple HPLC columns, including reversed-phase (RP), AQ-type reversed-phase, polar-embedded group RP columns, normal-phase, cation-exchange, anion-exchange, ion-exclusion, and HILIC (Hydrophilic Interaction Liquid Chromatography) columns. By controlling just three orthogonal method parameters - buffer concentration, buffer pH, and organic modifier concentration - users can adjust the column properties with pinpoint precision to separate complex mixtures.

Separation of Sulphonium Ions in Polar Organic Mode
October 4, 2005
The separation of steroids on Primesep 100 demonstrates the versatility of Primesep columns in both polar organic and ion-exchange modes in the separation of sulfonium ions. The high organic mobile phase retains methane sulfonic acid by a polar organic mechanism and separates methoxydimethylsulphonium and trimethylsulfphonium cations by polar organic and cation exchange modes. The separation method uses a mobile phase mixture of water, acetonitrile (MeCN, ACN), and trifluoroacetic acid (TFA) with evaporative light scattering detection (ELSD).
