EOI-0142/R2, Version 1.0
Only high-quality purge gases should be used with the PE Pyris 1. Minimum purity of 99.9% is recommended. 4.2.4 遵守 PE Pyris 1 和相关设备的开启和关闭程序。 Always observe the proper startup or shutdown procedures with the PE Pyris 1 and all related instruments. 4.2.5 通过天平室的气流流速始终控制在 40-60cc/min, 建议使用惰性气体来作为天平室的 冲洗气，如：氮气、氩气。 Always maintain a positive purge flow (40 – 60 cc/min) through the balance chamber at all times. An inert gas such as nitrogen or argon is recommended as a balance purge. 4.2.6 当加热炉的外套管移掉时禁止将加热炉抬升，否则将严重损坏 PE Pyris 1 的加热炉 和其他部件。 Do not raise the furnace when the clear Pyrex furnace tube has been removed. This will cause severe damage to the furnace and other components of the PE Pyris 1 analyzer. 4.2.7 当 PE Pyris 1 的加热炉在升温时，将其前面的塑料保护面板放下，以避免意外接触 高温的加热炉。 When the PE Pyris 1 standard or high temperature furnace is heating, keep the protective plastic shield on the PE Pyris 1 in the down position. This will protect you from accidentally touching the furnace when it is hot. 4.2.8 在切断电源和冷却风扇停止旋转前，不要移动 PE Pyris 1。 Do not attempt to move the PE Pyris 1 while it is on. Wait until the power is off and the furnace cooling fan has stopped spinning before moving the instrument. 4.2.9 在分析仪工作时禁止将其连接至 PE Pyris 1 的导线拔掉。 Do not remove cables from the PE Pyris 1 when the analyzer is turned on. 4.2.10 禁止触摸 PE Pyris 1 的加热炉开口，禁止向里面投入物体。 Do not touch the opening on the furnace lift mechanism or insert objects into the opening. 5.0 定义 DEFINITIONS
3.1 所有的实验室分析人员必须遵守本规范。 This instruction should be observed by all testing personnel. 3.2 分析人员使用前应先检查设备的校验日期，如果过期，则应向实验室主管或 QC 校验人 员汇报。 Visually check to make sure the calibration date on the instrument is not expired. If the instrument is expired, report it to a supervisor or the quality control calibration staff. 3.3 当仪器出现异常时应向实验室主管或 QC 校验人员汇报。 Malfunctioning instruments should be reported to both a supervisor and a QC calibration staff. 4.0 安全防护 SAFETY PRECAUTION
5.1 TGA：热失重分析仪 TGA : ThermoGravimetric Analyzer 6.0 工作程序 INSTRUCTIONS
注意：在使用 PE Pyris 1 进行实验或者校正前，应先对热电偶进行检查。将温度设定 至 100°C 后升温，如果热电偶校验正常，则显示的温度应非常接近 100°C。 NOTE: Prior to performing any experiment or calibration procedure, be sure that the thermocouple currently installed on the PE Pyris 1 is functioning properly. The thermocouple can be checked by programming the PE Pyris 1 to 100°C and checking the temperature displayed in the status panel. The temperature should be close to 100°C if the instrument is calibrated. 6.1 设备的启动和测量
2.1 本规范包括 Perkin Elmer Pyris 1 TGA 的校验，操作，维护程序。 This document covers the calibration, operation, and maintenance procedures for the Perkin Elmer Pyris 1 TGA. 3.0 职责 RESPONSIBILITIES
Start up and measurement 注意：在开机前确保动力气，天平气，参比气都已打开并调节到要求的流速。 NOTE: Make sure the Pneumatic gas, Balance gas and Reference gas are all open and adjusted to the requirement before the Analyzer turn on. 6.1.1 按下面的顺序打开系统： Turn the system on following order: 计算机 Computer 分析仪 Analyzer 6.1.2 运行 Pyris 软件，然后按下相关设备的按钮。 Execute the Pyris manager, then click on each instrument button. 6.1.3 等待每个设备的绿灯都亮起。 Wait until the green light comes to each instrument button (instrument window opens automatically). 6.1.4 将加热炉升起，待重量读数稳定后，按下“Zero”键去除样品盘的皮重。 Raise the furnace, after the sample weight reading is stabilized, then tare the sample pan by pressing the Zero weight button. 6.1.5 降下加热炉，在支架的保护下取下样品盘，放入样品，再将样品盘放回原处。 Lower the furnace; remove and fill the sample pan with the specimen while supporting the sample pan with platform. 注意：当取下或放回样品盘时，必须使用支架对样品盘进行保护。由于 Pyris 1 的天 平非常敏感易损，禁止再没有支架的保护下取下或放回样品盘。 NOTE: Always use the platform to work on sample pan. The weight balance is extremely sensitive, so do not change sample pan without platform support. 6.1.6 从“File”中打开适当的操作程序（每个程序可以根据特殊的要求进行修改）。 Open the appropriate method from the File menu (each method can be modified according to specific condition requirement). 6.1.7 打开“Sample Info”栏，填写 Sample ID, Operator ID, Comment, File Name，同 时检查初始状态栏并输入正确的系统参数。 Select the Sample Info tab and fill in the Sample ID, Operator ID, Comment, and File Name. Also check initial state tab and program tab for proper parameter set up. 6.1.8 装入样品盘，升起加热炉。 Load the sample pan, then raise the furnace. 6.1.9 输入初始温度，然后点击“Go to temperature”键。当温度升至设定的初始温度 后，点击“Sample weight”键称量样品重量，再点击“Start/stop”键，系统进入 自动运行状态。
