11.5 Using a USB Flash Drive as a User Folder
To use a USB flash drive as a user folder to keep your reports, insert your USB flash drive into the front USB
port and wait 5 to 10 seconds and the USB icon will pop up. (
Note
: The icon loading time depends on the
specification of the flash drive. It is recommended to format your flash drive in the FAT or FAT32 file system prior
to using it with the Spex NanoSNAP.) You can also use the USB flash drive to transfer the reports between the
Spex NanoSNAP and your computer.

12. Maintenance
12.1 Cleaning the Unit
Please avoid liquid spilling onto or into the unit. Liquid may damage the Spex NanoSNAP internal components.
In addition, periodically wipe it clean of dust and other residue that comes with normal operation of the unit. Use
a soft, lint-free cloth and deionized water.
12.2 Cleaning the Quartz Glass
Add deionized water on the sample window, lower the detection arm and wipe with a lint-free wipe. 70% ethanol
or isopropanol can also be used on the surface to clean both the sample window and the cover window.
It is better to clean the quartz glass every time before starting and after finishing experiments. It is also
recommended to clean the quartz glass when exchanging different concentrations of samples.
Note:
1. Use only a dry, soft, lint-free cloth to clean the front scree.
2. Do not use a spray bottle to apply water or any other solutions onto any surface of the instrument as the
liquid may damage internal components.
3. Do not use hydrofluoric acid (HF) as the fluoride ion will dissolve the coating on the surface.
4. Do not use an acid solution on the pathlength selector as it will damage the metal part and affect the
pathlength.
12.3 Annual Maintenance
For the best performance, it is suggested to do annual maintenance on the Spex NanoSNAP. It includes light
path confirmation and nano-coating layer recoating. Please contact your local Spex distributor for service.
12.4 Replacement
When the surface of the quartz glass has been damaged or contaminated, please contact your local Spex
distributor for exchange service.
