Application Column
BIST B+
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 Separation of Neurotransmitters
November 25, 2011
The neurotransmitters dl-DOPA, creatinine, hydroxytryptophan (5-HTP), and serotonin are separated in less than 4 minutes on a short 50 mm Primesep 200 column. The HPLC separation uses a mobile phase of water, acetonitrile (MeCN, ACN) and trifluoroacetic acid (TFA) and UV detection at 250 nm. Ion-pair reagents were not needed for retention of these polar, hydrophilic compounds, instead, a combination of ion-exchange and reversed-phase interactions were used.
| Column | Primesep 200, 4.6×50 mm, 5 µm, 100A |

| Buffer | TFA – 0.05% |
| Flow Rate | 1.0 ml/min |
| Detection | UV, 250 nm |
| Class of Compounds |
Drug, Acid, Hydrophilic, Ionizable, Hormone |
| Analyzing Compounds | dl-DOPA, Creatinine, Hydroxytryptophan (5-HTP), Serotonin |

HPLC Separation of Creatine, Creatinine and Histidine with MS Conditions
January 13, 2005
Creatine, creatinine, and histidine are all important amino acids in the human body. All of these can be separated by liquid chromatography. The mobile phase contains acetonitrile (MeCN), water, and phormic acid. Smaller 3 µm particle columns are available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation of impurities in preparative separation. It also suitable for pharmacokinetics.

HPLC Separation of Creatine, Creatinine and Histidine
January 13, 2005
Creatine is produced by the body and plays a major role in recycling ATP. It also stabilizes pH in certain tissues. Creatine can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains acetonitrile (MeCN), water, and TFA. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particle columns are available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation of impurities in preparative separation. It also suitable for pharmacokinetics.
