Product Name: LB5500 Large Area Automatic Low Background Alpha/Beta Counting System

Product Description

Description
Large Area Counting System

The Tennelec LB5500 is designed for counting large samples, up to 12.7 cm (5 in.) in diameter. Built on the same foundation of quality and innovation as other Series 5 systems, the Tennelec LB5500 offers low background performance for applications requiring a large area counting system. The added capabilities of Eclipse Control and Analysis Software make the LB5500 a state-of-the-art counting system that easily integrates into today’s count room. Specially designed detector windows provide the Tennelec LB5500 with excellent counting efficiency exceeding current regulatory requirements.

Whether counting large area air filters or for methods requiring additional sample amounts, the LB5500 is the system of choice.
Enhanced Low Background and Productivity – Simply the Best

Due to increasing environmental regulations to reach lower detection limits, sample count times have increased reducing the overall sample throughput in the laboratory. The Tennelec LB5500 incorporates new technology to reduce system background and increase sample throughput. Using an improved guard detector, the system sensitivity for high energy, cosmic background is increased, enabling the anti-coincidence circuitry to detect and reject more spurious background events.

The beta background for the LB5500 has been reduced by as much as 25% over older systems. Beta backgrounds as low as 3.0 cpm can be achieved. This means that the system can count almost twice as many samples for a given detection limit as a counter with a beta background of 5.0 cpm.
Passive Metric Shield

Using a graded shielding system, the LB5500 counts large area samples with more accuracy than any other low background counter. The passive shield system provides 10 cm (4 in.) of low background lead surrounding the detector. The shield comprises standard 5 x 10 x 20 cm metric lead bricks which weigh no more than 12 kg (25 lb) each for safety and ease of assembly. This lead is secured within a steel housing for further safety and to ensure minimal shifting.
Time Proven Reliability

The sample changer of the LB5500 is time and field proven. The highly reliable design of the automated sample changer transports and counts samples day after day providing worry free operation. When work counts and time is precious, count on a Tennelec system to deliver results and reliability.
Ultra-Thin Detector Windows

The standard gas flow detector of the Tennelec Series 5 family of systems incorporates a high performance pancake-style 12.7 cm (5.0 in.) detector. The entrance window of the detector is made with state-of-the-art technology and special materials to provide the highest counting efficiency and the lowest alpha background of any counter. Standard detector windows are 80 mg/cm2 with 500 mg/cm2 window as an option.
Positive Sample Identification and Bar Code – The Advantage

Today’s changing requirements demand sample identification that is maintained through the counting data. Data defensibility is a priority.

The Tennelec LB5500 incorporates unique carrier and sample identification systems to maintain chain-of-custody. An optional handheld bar code scanner allows input of sample information directly into the Eclipse software for improved chain-of-custody verifiability.

As the sample is counted, the carrier ID or sample bar code are automatically captured by the Eclipse software and stored with the sample count data forming the missing link in sample custody in the count room. 

Tennelec sample carriers are washable for easy cleaning and decontamination. Each carrier is permanently coded with a unique number that is non-removable after numerous washings.
Circuitry So Advanced, It Thinks for Itself

The advanced electronics package of the Series 5 family of counting systems provides the most advanced control and monitoring system available. The Series 5 incorporates hardware diagnostics which continuously monitor internal and external parameters including gas pressure and flow, system voltage, power distribution, sample and guard counts, and other system critical parameters. The user is alerted on the front panel if any of these parameters fall below normal operation thresholds. This allows you to take immediate action when a problem arises.

Human Factor Engineering

Often computer controlled analytical equipment requires additional laboratory space for the computer system and peripherals. The LB5500 answers that problem with an integrated mobile cart that provides all of the support necessary for the gas tank, computer system, monitor and printer. The articulating monitor support provides adjustable viewing angles without requiring additional space on the desktop. The retractable shelf opens to hold printer and supplies.

The LB5500 is designed to be a completely integrated, self contained counting system. The LB5500 has the industry’s smallest footprint for a large area counting system, so it takes up less space compared to other large area systems.
