Analysis and Comparison of VOCs Monitoring Technology

Analysis and Comparison of VOCs Monitoring Technology

Sensor technology: Common sensors for PID, FID; PID sensor response to low alkanes; FID sensor sensitive to hydrocarbon; Both monitoring accuracy up to PPb, but can not distinguish between VOCs species; Commonly used in hazardous area alarm, indoor air monitoring ;

Chromatography: The total amount of VOCs and characteristic components can be measured by column separation; however, the analysis cycle is long; it is generally used for on-line monitoring of fixed pollution sources;

Mass spectrometry technology: high sensitivity (ppt), short response time, measurement of many components, no calibration; but the price is relatively expensive; generally used in laboratories, hospitals, environmental emergency / traceability monitoring;

Spectral Technology: Commonly used technologies are FTIR, DOAS, TDLAS; fast response, generally used for regional ambient air monitoring / pollution source monitoring.

Uhmwpe Rope
UHMPE has many names: Ultra-high-molecular-weight polyethylene (UHMWPE or sometimes shortened to UHMW), also known as high-performance polyethylene (HPPE).
Manufacturers of ropes for boat use and general marine applications wax poetic and can only speak in superlatives when describing HMPE!
The characteristics of UHMWPE Rope
● UHMWPE Rope does NOT absorb water.

● HMPE feels very slippery to the hand.                                             

● Dyneema® and Spectra® are not weakened when wet as nylon is.

● Has a density of as little as .95 and floats on Sea Water
● It is stong. It is twice as strong as hardened steel (per unit area)
● HMPE has a very low coefficient of friction. In this it is similar to Teflon which is very slippery.
● Great abrasion Resistance
● UHMW-PE is self-lubricating
● UHMW-PE has good UV resistance.
● Low Elasticity.
