Jerome J405 Mercury Vapor Analyzer

Performing a sensor regeneration Perform a sensor regeneration by following these steps:

• Connect the line cord/AC adapter power supply between the connector on the back of the J405 and an AC power outlet or connect the external battery pack to the back of the J405.
• If the instrument is not already turned on, press the I/O power button to turn it on.
• Press the RIGHT arrow button (►) to enter the main menu.
• Press the DOWN arrow button (▼) to move the cursor to Regen.
• Press the RIGHT arrow button (►) to select Regen from the menu.
• Press the ENTER/START button on the keypad to select Regen Now from the Regen menu.
→The instrument will respond with "Perform Regen Using EXTERNAL POWER?"
■ Press ENTER/START to proceed or ESC to exit.
→The instrument display will warn "Do Not Disconnect External Power while Heating"
■ Press ENTER/START to proceed or ESC to exit.
→The instrument will now begin a 45 minute regeneration cycle, indicated by Regeneration in Progress on the display. Do no interrupt this cycle. For a complete description of this process, see page 20 of the user manual.
■ If any error message appears on the siplay, see the "Troubleshooting" section beginning on page 35.
• Ensure the instrument has been powered on for at least five (5) minutes prior to sampling.
• The instrument is now ready to sample.
• Press the SAMPLE BUTTON at the end of the handle of the J405 to start a 12 second sampling cycle.
• When the instrument measures mercury vapor, the 0.00 µg/m3 display will be replaced with a value.
• To ensure the input to the instrument contains no mercury vapor or mercaptans, use a Zero Air Filter (AZI P/N Z2600 3905). The Zero Air Filter cleans the air sample and should produce sample readings of 0.00 µg/m3. Therefore, use the filter to:
■ Equilibrate the instrument to temperatures that are higher or lower than the instrument. Sample every 15 seconds with the filter installed until the reading is 0.00 µg/m3.
■ Identify contamination within the unit.
■ Confirm the presence of mercury vapor when readings are elevated. Install the filter and verify that the readings decrease with the filter installed.
• The instrument is designed for ambient air monitoring.

WARNING:

DO NOT allow the probe or the instrument's intake to be exposed to ANY liquid.
DO NOT obstruct the intake or exhaust ports of the J405, as this could cause errors in readings and damge to the flow control system.

• The instrument is not explosion proof.
• Perform sensor regeneration before each day's use.
• Perform another sensor regeneration after each day's use.
• Perform sensor regeneration after 30 days of storage or inactivity.

AZI at a Glance

Arizona Instrument is an ISO 9001:2000 registered company that designs, manufactures, and markets Computrac® precision moisture analysis instruments and portable and fixed Jerome® gas analyzers. We provide complete pre- and post-sale customer service including application development, training, and instrument calibration and repair.

Computrac® Vapor Pro® moisture analyzers detect moisture levels as low as 10 ppm, or 10 mg, in samples as small as 10 mg utilizing moisture-specific sensors to eliminate volatile interferences. Computrac® MAX® moisture analyzers measure moisture content as low as 0.005 percent in as few as 3 minutes. These instruments are durable, easy to use, and equally suitable for the production floor and the laboratory.

Utilizing patented gold sensor technology, the Jerome® 631-X measures hydrogen sulfide concentrations of 3ppb to 50ppm, while the Jerome® 431-X mercury vapor analyzer detects concentrations from 0.003 to 0.999mg/m3, all in just 13 seconds. The Jerome® 860 hydrogen sulfide monitor provides automatic, unattended, long-term monitoring of hydrogen sulfide gases in contained or hard to reach areas. The compact, battery powered 860 is water resistant and intrinsically safe. Accessories include a field test kit for easy verification of instrument calibration, a data logger for data acquisition and instrument programming, and software for connecting the analyzers to computers.

Mercury Effects

HEALTH HAZARD INFORMATION

* Routes of Exposure

Exposure to mercury vapor can occur through inhalation, and eye or skin contact.

* Summary of toxicology

1. Effects on Animals: Mercury vapor can damage the kidneys, liver, brain, heart, lungs and colon in experimental animals. It is also mutagenic and can affect the immune system. Rabbits exposed for a single 4 hour period to mercury vapor at a concentration of 28.8 mg/m(3) developed severe damage to the kidneys, liver, brain, heart, lungs, and colon [Clayton and Clayton 1981]. Rabbits exposed to 0.86 mg/m(3) for 6 weeks had significant brain and kidney damage, which resolved on cessation of exposure. Exposure to 6 mg/m(3) mercury vapor caused severe damage to the kidney, heart, lung, and brain of rabbits; however, dogs exposed to 0.1 mg/m(3) for 83 weeks had no microscopic indication of tissue damage [Clayton and Clayton 1981]. Mercury may injure the kidneys through an autoimmune mechanism [ACGIH 1991]. Mercury was mutagenic in eukaryotic cells [ACGIH 1991].

2. Effects on Humans: Mercury vapor can cause effects in the central and peripheral nervous systems, lungs, kidneys, skin and eyes in humans. It is also mutagenic and affects the immune system [Hathaway et al. 1991; Clayton and Clayton 1981; Rom 1992]. Acute exposure to high concentrations of mercury vapor causes severe respiratory damage, while chronic exposure to lower levels is primarily associated with central nervous system damage [Hathaway et al. 1991]. Chronic exposure to mercury is also associated with behavioral changes and alterations in peripheral nervous system [ACGIH 1991]. Pulmonary effects of mercury vapor inhalation include diffuse interstitial pneumonitis with profuse fibrinous exudation [Gosselin 1984]. Glomerular dysfunction and proteinuria have been observed mercury exposed workers [ACGIH 1991]. Chronic mercury exposure can cause discoloration of the cornea and lens, eyelid tremor and, rarely, disturbances of vision and extraocular muscles [Grant 1986]. Delayed hypersensitivity reactions have been reported in individuals exposed to mercury vapor [Clayton and Clayton 1981]. Mercury vapor is reported to be mutagenic in humans, causing aneuploidy in lymphocytes of exposed workers [Hathaway et al. 1991]. READ MORE

Evaluation of Portable Mercury Vapor Monitors and Their Response to a Range of Simulated Oil Processing Environments

K.J. Grice, L.D. Van Orman, and L.A. Young, Chevron Energy Technology Company, and C.R. Manning, Assay Technology, Inc.
copyright 2008, Society of Petroleum Engineers

Abstract
Portable mercury vapor monitors are relied on for quick decision making to determine safe work practice requirements. There is little specific information regarding their use limitations and/or potential interference data, especially in environments of high temperature/humidity and various concentrations of hydrocarbons (HC) and inorganic gases, as are commonly found in oil processing environments. This work was undertaken to objectively assess the accuracy of each monitor under ideal conditions and then assess the effects of potentially interfering conditions or substances on monitor accuracy. This data was used to highlight specific limitations and create field user guides.

A secondary objective was to compare the overall usability and user-friendliness of the monitors evaluated. The paper describes the experimental method used and results provided by several mercury vapor monitors exposed to known concentrations of mercury vapor while other variables such as temperature, relative humidity and the concentration of potentially interfering compounds were varied to simulate field measurement conditions. Two types of detection technology were assessed, Gold Film resistance and Cold Vapor Atomic Absorption, (CVAAS). All monitors were tested against a variety of potential interference compounds, e.g., organics, benzene, toluene, and inorganics, ammonia, sulfur dioxide, nitrogen dioxide and hydrogen sulfide. The testing revealed several strengths and weaknesses for each monitor. Negative interference was found with the Gold Film unit in high relative humidity (RH). All CVAA units showed positive interference with high organic concentrations. Poor repeatability across the entire exposure range is common. Survey technicians need to become familiar with the specific limitations of the survey meter used to accurately assess the work environment where mercury (Hg) vapors are present. READ MORE
