Net peptide content analysis without compromise
In the past, you had to compromise when determining the net peptide content (NPC) of lyophilized powder. Now the highly sensitive carbon and nitrogen analyzer, UNICUBE® trace, links it all:
Cost-per-analysis of 0.55 €
Sample prep of 3 min only
Sample size of less than 1 mg
GMP compliance
Highest accuracy and precision
Training for your staff
Need to measure additional elements and/or samples?
NPC can be determined just as easily with the “UNICUBE®”, which can measure C, H, N, S, O* and Cl*. In addition to peptides, both instruments can analyze a wide variety of samples such as fluorinated pharmaceutical compounds, chromatography resins, liquid fuels, and inhomogeneous soils.
*optional configuration
Delve into real data
The peptidic material is the only source of nitrogen in the lyophilized powder. Therefore, the NPC can be calculated once the absolute amount of nitrogen in the powder has been determined. 20 µg of nitrogen suffice to produce high-quality NPC data via the UNICUBE® trace. Explore how the nitrogen results obtained via the UNICUBE® trace compare to Bachem's certified values.
Did you know? NPC analysis via the UNICUBE® trace fully complies with USP <1057> method 7 procedure 2 and Ph. Eur. monograph 01/2008:02533 method 7B on total protein measurement procedures.

NPC analysis made easy
NPC analysis via the UNICUBE or UNICUBE trace only requires 3 minutes of manual sample preparation and as little as 5 minutes for the subsequent fully automated analysis. See how this compares to amino acid analysis:
