Certified Platform Launched with Introduction of Precisive 5

Precisive, LLC (USA), an innovator in unattended process monitoring systems for gas analysis, today launched its new TFS (Tunable Filter Spectroscopy) platform with the introduction of Precisive 5, a compact hazardous-area compliant package for unattended hydrocarbon process and natural gas analysis.

Precisive specialises in unattended, all-optical process monitoring sensors for a variety of natural gas, LNG/LPG/BOG, combustion, emissions and biogas applications; particularly where real-time hydrocarbon speciation is demanded. Quantitative analysis of alkane gases specifically C1 to C5 (methane, ethane, propane, butanes and
pentanes) and other light hydrocarbons are important in a variety of applications, including BTU measurement and quality analysis of natural and biogas products.

“From the beginning when we founded the company in 2007, we worked very closely with leaders in the natural gas industry to develop a product that truly meets – and exceeds – their technical and harsh operational requirements,” said Dr. Vidi Saptari, founder and president of Precisive, LLC.

Key features and benefits the Precisive TFS offers are: Fast-Response: real-time measurements for on-line hydrocarbon processing and natural gas analysis. Measurements performed in seconds, compared to minutes with GC-based systems; Multi-Component: multiple composition monitoring (ie C1 through C5 and CO2) from ppm to percent level calibrations; ‘GC-like’ Speciation: monitoring of complex hydrocarbon compositions with significantly faster-response than traditional gas chromatography systems that require physical separation of compounds before analysis can begin; Low-Maintenance: No requirement for instrument carrier gas, no requirement for calibration gases, nor instrument fuel gases. Greatly reduces cost, complexity, consumables and maintenance; Ease of Deployment and Use: Modbus communications interface enables remote and unattended deployment without constant operator intervention. Novice users can become very proficient with minimal training; Stability and Linearity: measurement linearity across the full range and stability in the presence of variations in operating temperatures, pressures, and humidity levels; Compliant for Global Deployment: North America Division System (Class1Div2, Groups A/B/C/D, T4, Type 4X), North America Zone System (Class1, Zone2, Aex nA IIC T4, IP66, Ex nA IIC T4, IP66), European Zone System (ATEX EX II 3G n IIC T4 Gc), and worldwide certification to IECEx standards.
