Wyatt Technology is to unveil its Dynapro Nanostar dynamic light scattering (DLS) instrument at Pittcon 2009.
The Wyatt Nanostar is a DLS designed to deliver versatility and stability, with more than twice the signal-to-noise of its predecessors, to ensure consistently high performance.
The Wyatt Nanostar features a dedicated static light scattering detector so it can measure hydrodynamic radii and absolute molecular weights.
The instrument also has a TCP/IP interface to allow it to be added to a laboratory network instantly and operated from anywhere with an internet connection.
The temperature control built in provides fast response times and wide temperature range, from 4C to 150C.
The Nanostar offers precise temperature control, with a stability of better than 0.01C over the entire range, and a proprietary thermal design that can change temperatures as quickly as 15C/min.
When operating below ambient temperatures, the Nanostar employs a dual-valve dry nitrogen flow that keeps the cell dry and dust-free.
The Nanostar's multi-mode fibres collect a larger fraction of the scattered light, which gives better performance for weakly scattering samples.
It also has the capability of detecting trace amounts of aggregation.
A double-density correlator is standard, which has 512 bins from 100nsec to 1h, and instead of having 16 bins in the first stage and eight in each subsequent stage, the Nanostar has 32 in the first stage and 16 in the higher stages.
In order to ensure that the Nanostar never goes out of range, it comes equipped with automatic attenuation over five orders of magnitude.
Non-perturbing and non-destructive, the Nanostar determines the hydrodynamic radius and absolute molecular weight of nanoparticles simultaneously.
The Nanostar can also be coupled with Wyatt's on-line multi-angle light scattering systems (Dawn and MiniDawn) for enhanced resolution of HPLC eluents.
