Summary
High-performance liquid chromatography (HPLC) enables rapid separation of small samples. Miniaturization has advanced techniques like isoelectric focusing for hemoglobin analysis and peptide isolation.
Area of Science:
- Analytical Chemistry
- Biochemistry
Background:
- High-performance liquid chromatography (HPLC) is a key technique for sample separation.
- Miniaturization of analytical techniques offers advantages in speed and sample volume.
Purpose of the Study:

- To apply these methods for hemoglobin analysis and abnormal peptide isolation.
Main Methods:
- Miniaturized high-performance liquid chromatography.
- Isoelectric focusing (IEF) with immobilized pH gradients.
- Successive enzymic hydrolyses.
- Precolumn derivatization for amino acid analysis.
Main Results:
- Effective and rapid separations were achieved on microquantities of material.
- Isoelectric focusing (IEF) was utilized for hemoglobin preparation.
- Abnormal peptides were isolated using successive enzymic hydrolyses.
- Amino acid composition was determined after precolumn derivatization.
Conclusions:
