TRIMARAN—H20超低值自动水中氚监测系统
TRIMARAN—H20超低值自动水中氚监测系统的样品流输入管线压力可达103 kPa.，通过压力调节阀可立即减小到2-3psi，每个调节阀配有一个开到100 kPa的压力释放阀，因此系统中的压力从不会超过100 kPa,，这样操作起来安全，也使得这款仪器成为6级核设备。

PLC CONTROL
PLC控制
Sampling of input lines and control of alarms and pumps is done by PLC unit placed inside of the System Control Module. There is an alarm provided in case of PLC failure as well as manual
override so that the operation can be continued manually until PLC is replaced. Manual operation is a backup system; the unit normally operates in automatic mode.
样品输入管线和报警与泵的控制由安装在系统控制模块内部的PLC装置完成，一旦PLC或手动超控故障则提供报警，以便在PLC被更换之前手动继续操控。手动操作是备用系统，仪器正常自动模式操作。
ROUTINE MAINTENANCE
日常维护
Scheduled maintenance of consumables is required. P-10 gas cylinder needs to be replenished every 2 months and sample water filters need to be replaced. Also, periodic check of the efficiency and background is recommended if there is a possibility of increased background contamination and due to standard life cycle of electronics components.
要求对消耗品定期维护，P-10气体瓶需要每两月续填，样品水滤网需要被更换，还有，如果有本底污染有增加的可能，电子组件正常使用寿命周期原因，推荐定期检查效率和本底。
ANNUAL INSPECTION AND SERVICE
年检与检修
It is recommended that the instrument be inspected and serviced on an annual basis to ensure continuing trouble free operation. All components of the instrument should be inspected and instrument re-calibrated.
推荐仪器每年检修以确保持续无故障工作。仪器所有组件都应检查并重新校准

ADVANTAGES OF PROPORTIONAL COUNTING SYSTEM VERSUS LIQUID SCINTILLATION
与液体闪烁相比，正比计数系统优势
Until recently, the only detectors capable of measuring very low levels of tritium in water were Liquid Scintillation Counting (LSC) based. However, the LSC approach has some obvious disadvantages, such as: the LSC fluid must be constantly refilled at a significant cost in labor, money, and space; LSC fluid is also hazardous material and mixing with tritium results in ’liquid mixed waste,’ which must be carefully stored, transported and disposed of.
直到最近，唯一能够测量极低水氚的探测器为液闪计数技术，然而，液闪方法有明显不足，如：LSC液体必须持续续满，费工，费钱和占用空间，LSC液体也是有毒物质，与氚混合导致 “液体混合废液”, 废液必须小心存储，运输和降解。
By utilizing proportional counting technology, the user only has to acquire a compact standard steel tank of proportional gas, which will last for more than a month and is available from a variety of suppliers. The P-10 counting gas is 90% Argon and 10% Methane, and is not toxic or combustible. Measurement via this method achieves same or better low-end sensitivity, without having to deal with LSC fluid and waste.
使用正比计数技术，用户需要一个紧致标准的正比气体钢容器，可用一个多月，供货方便，P-10计数气体90%氩气，10%甲烷，无毒不易燃。通过这种方法测量可达到相同或更好的低值敏感度，而且不用处理LSC液体和废物。
SAMPLE ENRICHMENT
样品浓缩
With LSC and proportional counting detectors, Overhoff has pushed tritium detection to the most sensitive limit. However, samples can be so dilute, even with large multi-liter detectors, there are not enough disintegrations per second for good measurements. This issue is overcome by concentrating or enriching the sample,. This may be accomplished using iterative processes to concentrate the tritium in water using phase change or other physical differences (not chemical processes since 1H, 2H, and 3H are chemically identical.) Overhoff scientists have developed their own iterative sample enrichment cycle, creating system sensitivities far beyond other automated flow-through systems.
使用LSC和正比计数探头，OVERHOFF已经将氚探测推到一个最灵敏的限值，然而，样品可能太稀释，即使用多升探测器，也没有足够的每秒衰变以达到良好的测量结果，这个问题通过浓缩样品被攻克，可以通过使用相变或其它物理差异（不是化学过程，因为1H, 2H, 3H化学性质相同）浓缩水中氚来完成。OVERHOFF科学家已经研发出自己的迭代样品浓缩循环，使得系统灵敏度远远高于其它自动流过式系统。
