A counting solution so advanced, yet easy to operate. The Tennelec Series 5 platform is the next generation of automatic low background systems, designed to count samples the way they are prepared in a laboratory. Sensible and smart, the Series 5 provides integrated intelligence to satisfy the most demanding applications and routine analysis. 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 Series 5 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 Tennelec Series 5 has been reduced by as much as 35% over older systems. Beta backgrounds as low as 0.5 cpm can be achieved. This means that the Series 5 family of low background counters can count twice as many samples for a given detection limit as a counter with a beta background of 1.0 cpm. Impressive performance from an impressive system. ShieldUsing a graded shielding system, the Tennelec Series 5 counts samples with more accuracy than any other low background counter. The molded shield system provides 10 cm (4 in.) of custom molded lead surrounding the detector. The shield comprises interlocking modules which weigh no more than 27 kg (60 lb) each for safety and ease of assembly. The sample changer of the Tennelec Series 5 family 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. The standard gas flow detector of the Tennelec Series 5 family of systems incorporates a high performance pancake-style 5.7 cm (2.25 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 µg/cm2 with 500 µg/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 Series 5 incorporates a unique combination of carrier and sample identification systems to maintain chain-of-custody. Two methods of sample identification are linked to the final data report. An optional hand held bar code scanner allows input of coded sample identification. The sample carrier is uniquely coded. The carrier ID or sample bar code is automatically captured by the Eclipse software and stored with the sample count data, forming the missing link in sample custody in the count room. The Series 5 can be optionally configured with an internal bar code reader to provide an automated sample identification system for the Sample Management Software applications. Only 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 to assure accurate results. 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. Often computer controlled, analytical equipment requires additional laboratory space for the computer system and peripherals. The Series 5 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 monitor support provides adjustable viewing angles without requiring additional space on the desktop. The retractable shelf opens to hold printer and supplies. The Tennelec Series 5 is designed to be a completely integrated, self contained counting system with the industry’s smallest footprint. Gas Stat Gas Conservation System Conventional low background counters have manual gas flow control and use the equivalent of a 1A gas cylinder on the average of once per six weeks. Changing gas supplies usually means re-verification of critical system calibrations which can be an unnecessary time consuming process. Not only time, but the impact on data quality can become significant issues when frequent re-calibrations must be performed, due to a change in gas quality. The Series 5 with Gas Stat sets a new standard in the industry for eliminating the high frequency of re-calibrations due to counting gas changes. The Series 5 incorporates a microprocessor controlled gas monitoring and control system that provides worry free operation. Gas Stat eliminates the need to adjust manual flow meters, and flow rates are digitally displayed in real time on screen. The normal gas flow rate is set by the operator through software control. The Series 5 hardware senses when the system is not counting samples, and automatically reduces the gas flow rate to a low quiescent flow to maintain detector gas quality. This prevents atmospheric impurities from diffusing into the detector and causing questionable results. When the user starts a count, Gas Stat automatically purges the detector and resets the flow rate to normal. Gas Stat uses a preset maximum flow rate for the detector purging; so, it is virtually impossible to cause window damage due to over pressurization. Gas Stat effectively increases the useful life of the gas supply, thereby reducing the frequency of instrument re-verification, saving time and improving the quality of counting data. Eclipse – Powerful and Flexible System Calibration The Tennelec Series 5 has been designed to take full advantage of computer based system integration. Series 5 XLB uses the Eclipse software to provide the optimum combination of power and ease of use for a low background system. Eclipse is a true 32-bit multi-tasking Windows application that uses an industry standard database for storage of count data. The Microsoft Access database also allows for easy interfacing to network systems, since it is ODBC compliant and supports SQL operations. Custom reports can be easily developed for your application or presentation using a powerful sophisticated reporting application. Final activity results can be viewed on-screen for each sample as it is counted. An intuitive, symbolic icon tool bar provides access to functions at the push of a button. No other counter can match the advanced automation capabilities and features of the Series 5 XLB and Eclipse Software. (please look at our rules and privacy policy) |
