产品特点：1900多罐采样系统1900 Multi-Canister Sampling System 1900多通道滤罐取样器是Entech的下一代解决方案，用于收集Silonite涂层罐中的空气样品，以便在实验室中通过GC / MS或GC / FID / MS进行详细分析。 显着改善的流动路径现在产生更少的遗留潜力相对于其他商业上可获得的采样器。 质量流量控制器和电磁阀已被淘汰，因为它们包含已显示脱气的弹性密封件挥发性有机化合物，使得难以将无VOC空白达到亚PPBv水平。 相反，1900年采用独特的方法来启动，控制和停止维护的采样过程既干净又易于维修的样品系列，确保多年准确收集时间积分罐样品。 一个完整的WIN10控制器集成在面板中，允许高级远程操作，减少了现场编程的需要。● 内置PC● CH1和CH2的易流量调节● 简单的系统校准● 偶尔采样到连续监测的选项订购信息：DESCRIPTIONPART #UNIT1900 – Multi-Canister Sampling System(Includes Touch Panel display, dual 0.2% accuracy 0-15 psia sensors, and dual isolatch valves)1900EAOptional 8-Position Expander1900-8CH-EXPANDEADC Inverter (for battery, solar, or fuel cell power)1900-01EA

产品特点：1800 罐采样系统1800 Canister Sampling System1800提供最高水平的仪器控制和任何罐采样系统的最宽复合回收范围。 1800可以扩展以满足您的需求，作为单通道，双通道或与Entech的1816型16位罐采样器一起运行。 电源逆变器也可用于远程站点的12 VDC操作。随附的Windows XP触摸屏平板电脑控制器具有WiFi功能，可在现场或远程进行状态和编程更改。 实时记录和检索采样历史记录，包括每个样品的开始/停止时间，压力和最大/最小/平均流量。 使用来自其他实时监视器的反馈，在本地安排采样时间或启动采样事件。 自动泄漏检查和流动有助于保持较低的空白水平并提高样品的完整性。Using the canister’s vacuum to drive sampling eliminates compound loss,contamination and carryover problems created by pressurizing the sample through a pump. Silonite coating of the flow path further enhances compound recovery. When used with Entech’s Silonite canisters, even reduced sulfur compounds, formaldehyde, and C2 - C8 carbonyls are recoverable.1816多罐采样器The 1816 Multiple Canister Sampler works with channel 1 of the 1800 for unattended lling of up to 16 canisters. Like the 1800, the 1816 uses Silonite tubing and ttings to minimize surface losses for improved polar compound recovery. Each position is automatically leak checked prior to sampling,creating a “pass/fail” status. If a leak is detected during unattended operation, the system can be programmed to skip the event or advance to the next leak-tight canister position.订购信息：DESCRIPTIONPART #UNIT1800 Dual Position Canister Sampler(Includes Touch Panel display, dual 0.2% accuracy 0-15 psia sensors, and dual isolatch valves)1800EADC Inverter (for battery, solar, or fuel cell power)1800-01EAChoose from the following Mass Flow Controllers.(One required for each sample position.
