Micro gas dilution from PPM to PPB using only one small precise instrument

Product catalog summary

Project Overview: The project, in collaboration with L’Universita’ degli Studi di Roma “La Sapienza”, focuses on semiconductor photocatalysis. It is managed by Dr.ssa Maria Laura Santarelli, a seasoned chemist and researcher with over 20 years of experience in polymers, materials, and petroleum-derived sciences.

Role of MCQ Instruments: MCQ Instruments played a crucial role by providing advanced gas blending technology, which significantly improved the efficiency and effectiveness of the experiments conducted at La Sapienza.

Technical Specifications:

High Dilution Ratio: Achieved stable flow dilution from 400 ppm to 500 ppb using MCQ Gas Blenders.
Micro Flow Rates: The GB100 Series allows precise control of flow rates from 0.1 ml/min to 500 ml/min without cut-off.
Software Automation: The PRO version software enables automated experiments, enhancing efficiency.
Flow Stability: The method ensures stable gas flow, crucial for low flow-range experiments.

Standard Procedures: The project involves measuring the photocatalyst's capacity to remove NOx using an air flow containing NO and NO2 at 1 ppmv, with a test time of 5 hours and a flow rate of 1.5 L/min. Traditional methods required multiple devices and were time-consuming and unstable.

Innovations and Benefits: The use of MCQ's GB100 Series and software reduced the need for multiple devices, minimized time and effort, and increased the number of experiments and results. This approach provided accurate and reproducible test conditions, overcoming the limitations of traditional methods.

Conclusion: The integration of MCQ Instruments' technology has revolutionized the experimental process at La Sapienza, offering significant time savings and improved accuracy in semiconductor photocatalysis research.

Micro gas dilution from PPM to PPB using only one small precise instrument-2

DESCRIPTION OF THE APPLICATION AND THE TARGET Standard dictates to measure the overall capacity of the photocatalyst in removing the nitrous oxide, NOx, using and air ﬂow containing NO and NO2 (1ppmv) within an average test time of 5,0 h in lighting condition and with a ﬂow rate of 1.5 L/min. The level of exhaust used is about 500 ppbv. Given the low stability and the diﬃculty to ﬁnd gas test cylinder in such low concentrations, we decided to use standard Mass Flow Controller to reduce through mixing ultrapure air at 500 ppbv of NOx tanks as balance with standard cylinders with a concentration...
