Electronic Signatures

Electronic Signature

Electronic signatures can be executed on any data collected in ASTRA or DYNAMICS under Security Pack mode. To perform an electronic signature, the user first specifies a signature meaning (such as responsibility, approval, or review) and description, then enters a unique user ID and password. The electronic signature is executed to the experiment log associated with the data, and shows up in the report associated with the experiment.

Multiple electronic signatures can be executed to an experiment. In the reported results, the software flags any electronic signatures that were made before the last modification. Failed electronic signature attempts are recorded in the system log with an alarm status for immediate notification of system administrators.

Wyatt Technology is the recognized leader in light scattering instrumentation and software for determining the absolute molar mass, size, charge and interactions of macromolecules and nanoparticles in solution.

Wyatt's line of multi-angle static light scattering products couple to size exclusion chromatography (SEC-MALS), field-flow fractionation (FFF-MALS), and stop-flow composition-gradient systems (CG-MALS). Our dynamic light scattering (DLS) products operate in traditional cuvette as well as on-line and automated, high-throughput modes. We also offer unique instruments for electrophoretic light scattering (MP-PALS), differential refractometry, and differential viscosity.
