The TruePeak Tunable Diode Laser Spectroscopy (TDLS220) Analyzer, is specifically designed for accurate, reliable and low maintenance measurement of volume percent (vol%) oxygen in process gas streams.
The TruePeak Tunable Diode Laser Spectroscopy (TDLS220) Analyzer, is capable of measuring Oxygen in a variety of process applications with gas temperatures up to 120 °C and pressures up to 100 psi under difficult conditions (corrosive and aggressive service).
The TruePeak Tunable Diode Laser Spectroscopy (TDLS220) Analyzer is one of the most robust oxygen analyzers available.
Measurements are rapid (5 seconds) and interference free, offering improved accuracy when compared to other oxygen analyzers.
The TruePeak Tunable Diode Laser Spectroscopy (TDLS220) Analyzer (or TDLS) measurements are based on absorption spectroscopy. The TDLS220 TruePeak Analyzer is a TDLS system and operates by measuring the amount of laser light that is absorbed (lost) as it travels through the gas being measured.
In the simplest form a Tunable Diode Laser Spectroscopy (TDLS) analyzer consists of a laser that produces infrared light, optical lenses to focus the laser light through the gas to be measured and then on to a detector. The electronics that control the laser and translate the detector signal into values representing the gas concentration.

Cracking is used to break down the long chains of hydrocarbons that crude oil is comprised of into smaller hydrocarbon chains. Cracking was originally done thermally, and continued until 1933, when the Houdry process for catalytic cracking was developed. The Houdry units were preferentially adopted in following years due to producing a much higher portion of higher octane gasoline during cracking. The process was improved once again and became known as Thermofor Catalytic Cracking (TCC) and involved the use of a moving catalyst bed. The first commercial TCC unit was developed in 1943 in Beaumont, Texas and it is speculated that TCC and Houdry units played a large part in the allied victory of World War II. Around the same time, MIT professors Lewis and Gilliland developed a Fluidized Catalytic Cracking Unit (FCCU) which involves passing just enough air though the catalyst that it floats, allowing it to function as a fluid. FCCUs have since become the dominantly produced cracking unit. FCCUs used in conjunction with catalyst zeolite Type Y have increased the yield (~45% of total yield from the feed) and octane rating of gasoline far above of what would be achievable with thermal cracking. As of 2011, catalytic cracking produced over 8,700,000 barrels of motor gasoline per day in the US alone.
