If total sulfur analysis is the name of your game, the Trace 700 and 800 series analyzers are what you need. There are a multitude of added features associated with total sulfur detection; find the combination that is right for you and fill out the online quote form to get a price.
SAMPLE INJECTION CONTROL
The difference between the 700 and 800 series analyzers is this device. The 800 series analyzers use micro-liter injection valves to inject an exact amount of sample into the carrier gas stream. The injected volume and rate of injection are selected to meet the requirements for the stream being monitored.
TOTAL SULFUR ANALYSIS
The outstanding characteristics of the Trace Technology hydrogen sulfide detector can be utilized for total sulfur measurement by means of converting all of the sulfur in a sample to hydrogen sulfide. The sample is blended with an excess of hydrogen and the blend passes through a heated quartz or ceramic tube. In doing so, the sulfur bonds are broken and hydrogen sulfide is formed. The outlet is connected to the Trace Tape hydrogen sulfide analyzer, resulting in an analyzer which is totally sulfur specific.
The Trace Technology total sulfur instrumentation combines unique design and performance features with the basic reducing furnace. The structure combines concentric tubes that are used in the reducing process. The sample is injected through the center tube into an oxidizing tube where the carbon compounds are oxidized to sulfur dioxide. The oxidized compounds then reverse flow into the reducing tube with an excess of hydrogen. The process of reducing the SO2 to H2S is further enhanced by oxidation and flow contact with the catalyst. This combination eliminates carbon-carbon bonding which can cause increased system maintenance.
LIQUIDS REMOVAL SYSTEM
In addition to measuring H2S in hydrocarbon liquids, the Trace series of instruments can reduce costs when abatement chemicals are used. In applications where chemicals are added to liquids to control H2S emissions, excessive margins can be reduced enabling the reduction of operating costs.
Using stainless steel instead of galvanized steel in the construction of the wiring conduits will reduce the risk of corrosion of the instrument; all of the conduits in the analyzer are replaced with their stainless steel counterparts.
This device is used to reduce a high pressure, supply pressure, or inlet pressure in one stage to a lower pressure. The pressure reducing regulator is designed to meet the stringent requirements of a process analyzer sample conditioning system. The low internal volume reduces lag time thus more nearly approaching real-time analysis.
This device is used to remove unwanted contamination in a system. Bypass filters allow a continuous sweeping action across the surface of the filter element. This sweeping action prolongs the life of the filter element and also insures the sample that passes through the element is representative of the current system condition.
The calibration tap point includes the connection fittings and tubing together with a three-way ball valve to easily connect calibration gas to the analyzer.
The alarm provides contact output to alert operations in the event of one of the following fault conditions:
SMARTalk provides complete remote operation via personal computer or host with true bidirectional communication. The operator does not have to travel to the measurement site to alter operation, initiate calibration, or view data. Controls, reports, and data are available at lab or office via a personal computer link. Remote access reduces the chance of "no fault found" service calls where on site trips find no fault with the equipment.
LCD GRAPH DISPLAY
The display is a paperless chart recording of the concentration with selectable time scale to make comparisons and graphically display operating trends over time.
A miniature DC powered rotary vein pump to provide sample flow from atmospheric sources. This option is necessary if there is no line pressure.
A heater with thermostat control is integrated into the cabinet which provides freeze protection throughout the cold winter months. This will prevent the humidifier solution from freezing in sub zero temperatures causing the unit to malfunction. This will drop the lowest allowable operating temperature 15°C to -10°C.
The vaporizing regulators vaporize a liquid into a gas then perform a single stage pressure reduction on the gas. Pressure drops through pressure regulators may cause cooling which allows liquid to form. The vaporizing regulator puts heat back into the flow media to insure that is stays a gas.
A hard copy record of 4-20 mA output is available in:
The auto calibration provides software algorithm, contact outputs, solenoid valves, tubing, and customer connections for automatically calibrating analyzer at preselected time intervals.
The cabinet stand is a pipe stand with mounting holes for outdoor and indoor use.
TRACErase uses technology based on a catalytic combustion process to oxidize vented samples thus preventing fugitive emissions from entering the atmosphere without causing back pressure on the analyzer. Packaged to provide explosion proof protection, this unit may be used in hazardous locations.
REMOTE DISPLAY AND ALARM
This option uses the 4-20 output from the analyzer to generate a digital display of concentration and adjustable alarm contact outputs
This option allows the analyzer to select and analyze more than one sample source. This is ideal for any situation where more than one sample source is present.
A new option available on the TRACE analyzer is a light behind the LCD to make operation even more user friendly.
