The Yokogawa TDLS8000 Tunable Diode Laser Spectrometer

TDLS8000
The Yokogawa TDLS8000
The Yokogawa TDLS8000 can quickly make in-situ measurements of gas concentrations in combustion and heating processes that are employed in the oil, petrochemical, electric power, iron and steel, and other industries.

Companies are always looking for ways to optimize processes by saving energy, reducing CO2 emissions, and improving safety and one way to do this is by optimizing the air-fuel ratio in the combustion process. To accomplish this, sensors are needed that can continuously monitor the concentration of O2 and CO+CH4 in the radiant section of fired heaters.

Product Features

  1. Highly reliable measurement - The TDLS8000's laser module includes a newly developed reference cell board that improves the reliability of absorption peak detection, which is an important step in the spectral area method. In addition, the receiving unit employs a new auto gain function that can automatically optimize detection sensitivity depending on the measurement object. By increasing the signal-to-noise ratio (S/N ratio), this improves the reliability of measurements taken in coal combustion and other processes where there is high particulate loading. Designed to meet the requirements for SIL2 certification (certification pending) defined by the International Electrotechnical Commission (IEC), the TDLS8000 will play a key support role in ensuring the safe operation of plants.
  2. Improved operability and maintenance efficiency - The TDLS8000 comes with a large 7.5-inch LCD touch screen that can display a greater variety of data. The touch screen replaces the push button interface used with preceding models, making the setting of parameters easier and more intuitive. The light source module containing the laser diode is fully sealed and damage resistant. To facilitate troubleshooting and reduce downtime, this module is able to store up to 50 days' worth of raw data that can be accessed anywhere in the world by, for example, a Yokogawa response center.
  3. Compact size - The redesigned TDLS8000 is just three-quarters the size and weight of the preceding model, allowing it to be installed in a greater variety of locations.

In Situ Microbial Fermentation Analysis and Mammalian Cell Culture Analysis - for R&D and Mass Production

Biopharmaceutical production processes, including microbial fermentation and mammalian cell culture vary greatly with organisms behaving differently and metabolizing at varying rates. With in-process measurements you can monitor the key parameters and optimize the fermentation or cell culture processes. Using a bioprocess analyzer allows for rapid analysis of many different properties with one quick measurement.

Both Fermentation and Cell Culture processes in a single, closed vessel can benefit greatly from in-process or in situ chemical analysis. Whether you are working with small laboratory scale reactors or large scale production equipment, Near Infrared (NIR) analysis can make your processes more efficient and optimized. NIR provides useful analysis for R&D, Scale-up, Process Development and full-scale production. Large-scale fermenters and bioreactors can hold as many as 250,000 gallons of raw material, which may be in process for hours or several weeks. An NIR analyzer can monitor both the start up media and emerging product on-line, despite the thick, soupy nature of the material.

Additionally you can get online measurements of Glucose, Glutamate, Acetate, Lactate, Ammonia,
Cell Density, Product Titer/Protein with NIR analyzers. These properties can be measured In-Situ or in the lab. If you have many fermentors/reaction vessels,  optical multiplexers will allow one analyzer to monitor up to 20 measurement points, sending all the valuable data to your process control system automatically.

In mass production the electrical power savings alone can provide payback for an NIR analyzer within a few months. Added product yield from improved process control also generates enormous payback, as well as reducing the occurrences of lost batches.

GC8000 Process Gas Chromatograph
Yokogawa
Gas chromatography is a common analysis tool employed in many areas of the process control industry, including oil and gas, pharmaceutical, chemical, and others. Yokogawa Corporation of America developed instrumentation to provide top tier GC performance with their GC8000 Process Gas Chromatograph for use in oil and gas, and other industrial applications.

In addition to the ruggedness and reliability for which Yokogawa gas chromatographs are well known, the GC8000 brings a number of innovations and improvements to the company’s process gas chromatography product offering.
  • Color touchscreen HMI for easy operation
  • Advanced predictive diagnostics and software functions monitor key performance indicators during each analysis to verify analyzer is operating within proper tolerances.
  • Parallel chromatography enabled through the use of GC Modules provided as part of the GC8000. Virtual GCs can be set up inside a single GC with GC Modules to measure multiple streams simultaneously.
The graphics below expand on this overview of the GC8000 Process Gas Chromatograph, the culmination of Yokogawa’s 55 years of experience in the field. For more detailed information, or to discuss your application specifics, contact a product specialist.
