Standard Solution (NP80, N60, N50)
The NanoPhotometer
®
is recalibration free therefore it is not
necessary to review the photometric accuracy on a regular basis.
If the SOPs of a laboratory require a routine control of the
photometric accuracy standard solutions can be used.
Note:
Specifications of the standard solution are guaranteed for at least one year. Please see
expiration date. Once a vail is opened it can be used for 30 minutes.
Note
: Please read the Material Safety Data Sheet carefully prior to using this product.
IQ/OQ documentation (NP80, N60, C40)
The NanoPhotometer
®
IQOQ package consists of a Standard Solution and/or a Didymium Glass
Filter and a corresponding Excel-based software tool depending on the type of instrument. The Excel-
based software produces an automated report displaying all relevant data for an audit.
Note:
The IQ/OQ documentation is not available for the NanoPhotometer
®
N50.
Submicroliter Cell (C40 only)
The submicroliter cell provides the option of upgrading the
NanoPhotometer
®
C40 to a device that handles nanovolume samples as
well as cuvette samples. The sample volume range of the submicroliter
cell ranges from a minimum of 0.3 µl to 5.0 µl with the path length
options including 0.04 mm, 0.1 mm, 0.2 mm, 1 mm and 2 mm which
correspond to virtual dilution factors of 1:250, 1:100, 1:50, 1:10, and 1:5
respectively.
DiluCell (C40/NP80 only)
The DiluCell is a disposable cuvette with shortened path length for virtual
dilution of cuvette-based samples. Due to the reduced path length the
DiluCell provides an automatic dilution without the need of a physical
dilution of higher concentration samples. There are two different sizes of
DiluCells available DC 10 and DC 20 which allow an automatic 1/10 and
1/20 dilution of the sample respectively. Bypassing manual sample
dilutions reduces dilution errors and cross-contamination making DiluCell
ideal for GLP. Combined with small sample volume requirements and
bubble free filling, the DiluCell allows for convenient spectrophotometric
analysis from 340 - 950 nm.
