The Wyatt DNDC kit is ideal for use with a Wyatt Optilab for the determination of dn/dc values in the "batch" mode. This kit also enables you to calibrate an Optilab using NaCl standards (to ensure accurate concentration measurements are made in the flowing mode) and facilitates other batch measurements such as creating a Zimm plot with a MALS detector.

The centerpiece of the DNDC kit is a specially-designed injector module (pictured below) that makes batch RI measurements a breeze. Connect your syringe pump or HPLC pump to the injector inlet, and follow up with your RI instrument for a simple and super-stable RI measurement platform. Creating a stable RI measurement environment is crucial for accurate dn/dc measurements and RI instrument calibration, as the Optilab detects even the slightest changes in refractive index.

The standard injector model operates at pressures up to 500psi, intended for "off-line" batch measurements involving the Optilab alone. A high pressure version of the DNDC kit is available to meet your solution injection needs at low and high operating pressures (up to 7000 psi), with your Optilab and possibly additional instruments involved. Both models are compatible with common organic and aqueous solvents.

The kit includes one injection module, a 1mL injection loop (standard), a handful of syringes to help get you started, and cabling for making an injection signal connection to a Wyatt instrument.
