Infrared Spectrometer

Introducing Direct Detect, the first infrared (IR)-based biomolecular quantitation system

Just spot your sample, blank, and read! No sample prep, standard curves, messy cuvettes or liquid waste. By using the mid-IR spectrum, the Direct Detect system distinguishes proteins and peptides from interfering sample components, providing more accurate results without the pitfalls of colorimetric assays.

Goodbye, Bradford Assays!

How Direct Detect gives you better quantitation:

IR spectrometry measures amide bond absorbance for higher reproducibility across all proteins and peptides
Improves speed and accuracy over traditional colorimetric assays
Works in the presence of detergents and reducing agents
Also detects other biomolecules, including nucleic acids, lipids and carbohydrates, thus providing a broader range of biomolecular detection and more information of your sample components
Preserves precious samples—requires only 2 μL per analysis

Now quantify long aliphatic chains in lipids and detergents:
