Testing Methods for Verified Peptide Analysis
Lab Centro uses established analytical workflows to evaluate identity, purity, contamination risk, and supporting quality data. Each method is selected to match the sample, the testing objective, and the level of documentation required.
Core Methods Used by Lab Centro
Our testing programs combine orthogonal methods so results are not based on a single data point. Method selection depends on the analyte, matrix, specification, and reporting scope.
HPLC / UPLC
High-performance and ultra-performance liquid chromatography support peptide purity profiling, peak separation, and impurity review.
LC-MS / HRMS
Mass spectrometric methods help confirm molecular identity, characterize expected masses, and investigate unknown or degradation-related signals.
ICP-MS
Inductively coupled plasma mass spectrometry is used for trace elemental and heavy metal assessment where applicable.
GC-MS
Gas chromatography mass spectrometry supports residual solvent evaluation and volatile compound analysis when required.
Karl Fischer
Water content testing helps assess moisture levels that may affect sample stability, handling, and interpretation.
Ion Chromatography
Ion-based analytical methods can support targeted ionic contaminant and counterion assessment in suitable sample types.
Method Selection
Why Method Fit Matters
A reliable COA depends on using the right method for the right question. Lab Centro focuses on traceability, controlled methodologies, documentation, equipment qualification, quality control, and reproducibility.
Testing Methods FAQ
Common questions about how analytical methods are selected and used.
How is the testing method chosen?
Method selection depends on the sample type, requested panel, target analytes, specification criteria, and the level of analytical confirmation needed.
Does one method provide a complete answer?
Usually not. Independent testing is strongest when multiple complementary methods are used to confirm identity, purity, and potential contamination risks.
Can methods be combined in one package?
Yes. Testing packages and custom panels can combine chromatographic, mass spectrometric, elemental, microbiological, and supporting methods based on project needs.
Are raw analytical data available?
Reporting can include supporting analytical data and documentation appropriate to the service scope, helping clients review how conclusions were reached.
Do all samples need the same workflow?
No. Sample matrix, intended use, stability concerns, and acceptance criteria can all affect the most appropriate analytical path.
Can Lab Centro support custom analytical requests?
Yes. Custom analytical testing can be discussed when standard packages do not fully match the sample or reporting objective.
