Examples:
H2S Gas Detection
Key Challenge:
Accurately detect H2S down to low concentration levels in the presence of multiple, high concentration interferents (mercaptan, benzene, toluene, etc)
Present state of the art:
Photometers can detect H2S, but not in the presence of high concentration interferents. Best solution today achieves about ~100 ppm accuracy in the presence of these interferents
Photometer powered by Ometric MOC:
MOC technology enables 5X more accurate detection of H2S even at low H2S concentrations and high interferent concentrations
Better than 20 ppm H2S accuracy demonstrated in presence of 152ppm of interferents (100 ppm Mercaptan, 40ppm Benzene, 12ppm Toluene)
Caustic Solutions
Key Challenge:
Measure NaCl (0-20w/w%) and Na2CO3 (0-10w/w%) in ternary caustic mixtures containing NaOH (0-20% w/w%)
Present state of the art:
Photometers can detect NaOH in caustic solutions, but not NaCl or Na2CO3 due to multiple interferences.
Photometer powered by Ometric MOC:
MOC technology enables detection of both NaCl and Na2CO3 across the entire concentration ranges of interest in the ternary caustic solutions with accuracies far exceeding customer specifications of 0.5%:
<0.20% NaCl accuracy
<0.12% Na2CO3 accuracy
Semiconductor Solutions
Key Challenge:
Measure NH4OH and H2O2 in standard semiconductor solution while measuring the solution in-situ and in real-time without requiring sample conditioning over the temperature ranges of interest.
Present state of the art:
Photometers can detect NH4OH and H2O2 in semiconductor solutions, but not in-situ and in real-time without sample conditioning and not through the customer’s piping or tubing. Typical accuracies today are 0.25% and 0.30% for NH4OH and H2O2 respectively
Photometer powered by Ometric MOC:
MOC technology enables detection of both NH4OH and H2O2 in-situ and in real-time through the customer’s tube across the entire concentration and temperature ranges of interest.
MOC technology improves the accuracy over state of the art by 5X and 3.5X respectively:
<0.05% NH4OH accuracy
<0.08% H2O2 accuracy
GOR in petroleum
Key Challenge:
Measure Gas to Oil Ratio (GOR) in petroleum
Wire line and measure while drilling (MWD)
High temperatures (150-350 F) and pressures (up to 12500 psi)
Requirements:
GOR varies from about 0-1500 GOR units, with 2000 being about 50% gas
Photometer powered by Ometric MOC:
SEC <100 GOR units.
Dyes in Life Science Applications
Key Challenge:
Measure dye fluorescence in presence of competing fluorophores
Present state of the art:
Many instruments produced by many companies, all based on bandpass filters
Interference from competing fluorophores is a significant problem for many applications (e.g., real-time PCR; cytometry)
Photometer powered by Ometric MOC:
Decreases detection limits by a factor between 2 X and 10 X
Be less restrictive in their dye selections or,
Select less costly components
Corn Sweeteners
Key Challenge
Measure Fructose in the presence of glucose and other sugars
Present state of the art:
Photometers measure total reducing sugars (e.g., fructose + glucose, etc), 0-5% w/w, ±0.25%
Photometers measure brix, no direct photometer measurement of fructose in high concentration glucose
Photometer powered by Ometric MOC:
Fructose 45-55% measured ±0.5%
