HPLC Method for Analysis of Creatine and Creatinine on Primesep 200 Column
December 10, 2024
HPLC Method for Analysis of Creatine, Creatinine on Primesep 200 by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Creatine, Creatinine
Creatine is a naturally occurring compound found in muscles and is used to produce energy during high-intensity exercise. It is synthesized in the body from amino acids and stored in muscles for quick energy release. Creatinine, on the other hand, is a waste product produced from the breakdown of creatine. It is filtered by the kidneys and excreted in urine. The measurement of creatinine levels in the blood and urine is commonly used to assess kidney function, as high levels may indicate impaired kidney function or other health issues.
Creatine and Creatinine can be analyzed and separated using a Primesep 200 mixed-mode stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water, acetonitrile (MeCN), and phosphoric acid as a buffer. Detection is carried out using UV.

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 |
| Mobile Phase | MeCN/H2O – 80/20% |
| Buffer | TFA – 0.05% |
| Flow Rate | 1.0 ml/min |
| Detection | UV, 250 nm |
| Class of Compounds |

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.

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.
