Our Testing Process

Analytical methods answer different questions about a material. Our testing framework is designed to clearly document what was tested, which methods were used, and the results reported for each applicable lot.

  1. 1

    Sample Selection

    A representative sample from the applicable production lot is submitted for independent analytical testing.

  2. 2

    HPLC Purity Analysis

    HPLC evaluates chromatographic purity by separating and measuring components present in the analyzed sample.

  3. 3

    Identity Analysis

    When an appropriate identity method such as mass spectrometry is performed, the resulting molecular information can be compared with the expected characteristics of the target material.

  4. 4

    Additional Analysis

    Additional analytical measurements may be performed depending on the material, lot, and testing program.

  5. 5

    Lot-Specific COA

    Available analytical results are organized by lot and published through the Full Spec COA database.

Understanding Analytical Testing

Different Tests. Different Answers. A Clearer Picture.

No single analytical measurement describes every characteristic of a research material. Understanding what each method measures is essential when reviewing testing documentation.

HPLC Purity Analysis

Retention TimeDetector Response

High-performance liquid chromatography separates components within an analyzed sample and can be used to evaluate chromatographic purity.

Identity Analysis

m/zRelative Intensity

Identity testing evaluates characteristics of the analyzed material against expected reference information. The specific analytical method used should always be identified in the applicable laboratory report.

Additional Analytical Data

Depending on the testing program, additional analytical measurements may provide information beyond chromatographic purity or identity. Always review the lot-specific report to determine exactly what was tested.

Purity ≠ Identity

Purity and molecular identity are related but distinct analytical characteristics. A purity result describes what was observed using the stated purity method. Identity testing addresses a different analytical question. Neither should automatically be interpreted as evidence of other attributes that were not tested.

Always review the applicable laboratory report to understand:

  • • what was tested
  • • which method was used
  • • what result was reported
  • • which lot was analyzed

Every Result Should Be Traceable

Testing Should Follow the Lot.

Full Spec organizes testing documentation around individual lots so researchers can review the analytical information associated with the material being evaluated.

Common Questions

Testing FAQ

What does peptide purity mean?
Purity describes the proportion of the analyzed sample represented by the target chromatographic component under the stated analytical method. It is typically expressed as a percentage and is only meaningful relative to the specific method used to generate it.
Is purity the same as identity?
No. Purity and identity are distinct analytical characteristics. A purity result describes how much of the analyzed sample corresponds to the target peak under a stated method; identity testing addresses whether the material's molecular characteristics match those expected of the target compound. A high purity result does not, by itself, confirm identity, and vice versa.
What is HPLC?
High-performance liquid chromatography (HPLC) is an analytical method that separates the components of a sample and measures their relative proportions. It is commonly used to evaluate chromatographic purity.
What is mass spectrometry?
Mass spectrometry (MS) is an analytical method that measures the mass-to-charge ratio of ionized molecules, providing molecular-mass information that can be used, often alongside other data, as part of confirming a material's identity. It is one of several methods that may be used for identity testing.
What is a Certificate of Analysis?
A Certificate of Analysis (COA) is a laboratory document reporting the analytical results for a specific tested lot, including which methods were used and the results obtained. Full Spec publishes available COAs by lot in its COA database.
Why does lot-specific testing matter?
Manufacturing and testing happen in discrete batches, or lots. A result from one lot does not necessarily apply to another. Organizing testing documentation by lot lets researchers review the analytical results tied to the specific material they're evaluating, rather than a general claim about a product line.
How can I find the COA for a Full Spec product?
Visit the Full Spec COA database and search by product. Each product's COA history, including its current batch and past batches, is organized there when available.
