VUV Analytics - LUMA™
LUMA™ is a powerful new universal absorbance
detector for gas chromatography. LUMA is the
only Universal GC detector available that is
designed to be Sensitive, Selective and Simple
to operate.
LUMA acquires data in discrete wavelength
band from 120nm to 500nm. This broad range
includes the Vacuum Ultraviolet (VUV)) Region of
the electromagnetic spectrum. This region is
unique because all compounds absorb except
for typical GC carrier gases Hydrogen, Helium,
and Argon.
LUMA acquires data in 12 discrete wavelength
bands. Each
wavelength band can be configured as an
output channel in your CDS. Each output
channel is represented as an individual
chromatogram.
LUMA has the sensitivity required for the most
demanding trace level applications.
Benzene, a common carcinogenic compound is
highly regulated across multiple industries. In the
chromatogram to the left, LUMA can see
Benzene in Gasoline at an IDL of 500 femtograms
(~4ppb).
The compact VUV LUMA multi-channel detector was developed with laboratory productivity in mind and is powerful enough for R&D while being easy enough for routine analysis. Key capabilities of LUMA include:
• Sensitivity to sub-picogram levels, allowing for the detection of low-level analytes and impurities.
• Universal detection — nearly all compounds absorb, making it ideal for a wide range of applications.
• Channel Selectivity for compound identification and simple deconvolution.
• Channel Flexibility. LUMA acquires up to 12 independent channels (wavelength bands) of data. This flexibility allows for a wide range of analysis to be performed on a single detector — potentially eliminating other detection techniques and reducing the number of sample injections required.
• User-installable in less than one hour. LUMA installs directly on top of existing Agilent 68, 78, and 8890 GCs.
• LUMA does not require special or separate gases. All gases are supplied through the GC and AUX EPC.
• LUMA works with existing laboratory Chromatography Data Systems so there is no new software to learn, which minimizes training.
• Low Cost-of-Ownership. LUMA uses minimal consumables like a deuterium lamp that is rated for 2,000 hours.
