Microscopy Suite Equipment Fees

Fees/rates for use of equipment in the Microscopy Suite determined through analysis by Government Costing, University of Illinois. In effect starting July 1, 2018; subject to change.


NICOMP 380 ZLS Particle Sizer

Dynamic Light Scattering is a method of determining the size of particles in a liquid by measuring the intensity of light scattered from the particles to a detector over time. As the particles move due to Brownian motion the light scattered from two or more particles constructively or destructively interferes at the detector. By calculating the autocorrelation function of the light intensity and assuming a particle distribution it is possible to determine the sizes of particles from 1 nm to 5 um. This instrument is also capable of measuring the Zeta potential of particles.

Notes:

* The fee for use is added to our purchase cost for the specific precious metal (gold, gold-palladium, or platinum) expended during coating. Gold and gold-palladium are charged at $0.30/nm, and platinum is charged at $0.45/nm. The added fee is easy to determine for the dual-metal evaporator, for which total thicknesses are reported in nm. For the sputter coaters, at 65 mTorr and 40 mA, gold coats at 3 nm/10 seconds, gold-palladium coats at 1 nm/10 seconds, and platinum coats at 1 nm/10 seconds. So a standard 70-second coat of gold will cost an additional (21 x 0.30) $6.30, a 70-second coat of gold-palladium will cost (7 x 0.30) $2.10, and a 70-second coat of platinum will cost (7 x 0.45) $3.15.

**The Xradia NanoCT system requires staff setup of the sample before X-ray collection.

***The actual hourly cost for this instrument is $91.31. The Beckman Institute subsidizes the TEM at a rate of $41.31 per hour for Internal university users. Enterprise Works users are charged the full $91.31 per hour.
