  • 01Peptide purity assessment
  • 02Related substances profiling
  • 03Raw material quality control
  • 04Finished product release testing
  • 05Batch-to-batch consistency verification
02METHOD OVERVIEW

Purity testing at Standard Analytica uses reverse-phase HPLC with UV/PDA detection to determine the chromatographic purity of your compound. Purity is calculated as a percentage of the main peak area relative to all detected peaks.

This method is the gold standard for assessing synthetic peptides, active pharmaceutical ingredients, and research compounds. Related substances and impurities are identified and quantified as part of the analysis.

All methods are developed and validated in accordance with ICH guidelines. System suitability is verified at the start of each analytical sequence to ensure data integrity.

04TESTING PROCESS
01

SAMPLE INTAKE

Your sample is received, logged into our LIMS system, and assigned a unique tracking identifier. Sample integrity is verified and documented upon receipt.

02

PREPARATION

Samples are weighed, dissolved, and diluted according to validated preparation protocols. System suitability standards are prepared concurrently.

03

ANALYSIS

Samples are injected into our HPLC system. Peaks are separated chromatographically and detected via UV/PDA. Area normalization is used to calculate purity percentage.

04

REPORTING

Chromatographic data is integrated and reviewed by senior analysts. A comprehensive report with purity calculations, peak identification, and raw chromatograms is delivered.
