保存在巴黎的国际计量局总部国际千克原器,在2007年的一次检查中,发现有118年历史、用铂和铱混合铸造的圆柱形铸件——国际千克原器减轻了大约50毫克。2013年1月初,德国最新一期《计量学》杂志刊载研究报告称,作为标准质量单位的国际千克原器因表面遭污染而略有增重。
由此联想到FDA不承认内置砝码校准的问题,内置砝没有处在“千克原器”的真空、恒温、恒湿的环境,一年四季温度、环境湿度处在不断变化过程,降温和环境湿度增加时,总会有水分子凝结在内置砝码表面。升温和环境湿度下降时,总会有吸附在FDA内置砝码上的水分子解吸附,内置砝码自身的质量本身就是不断波动的过程,这样理解FDA不承认内置砝码的校准是否正确。请明白的战友指正。
我们公司想组建一个新的实验平台,仪器设备都得我们自己选,请问哪位有好点的分析天平(万一之一)推荐的,谢谢了。
希望和大家分享这一点小小的经验。
简介:天平,亦称天秤,在物理学上,是一种利用作用在物体上的重力以平衡原理测定物体质量或确定作为质量函数的其他量值、参数或特性的仪器。由支点(轴)在梁的中心支着天平梁而形成两个臂,每个臂上挂着一个盘,其中一个盘里放着已知质量的物体,另一个盘里放待测物体,固定在梁上的指针在不摆动且指向正中刻度时的偏转就指示出待测物体的质量。向左转|向右转基本结构:
普通天平主要由立柱、横梁、吊挂系统、底座和制动装置组成。立柱垂直固定在底座上,用以支撑横梁。立柱下部装有分度牌,顶部装有托架,在天平不工作时支托横梁。在横梁中部装有一把中刀。天平工作时,中刀搁置在与升降杆顶端连接的刀承上,作为支点。中刀两边装有两把边刀,分别作为重点和力点,起承受和传递载荷的作用。中刀下横梁底面装有指针,指针上固定有可上下移动以调节横梁重心位置的重心砣,它起调整天平灵敏度的作用。横梁顶部刻有分度标尺,标尺上有一移动游码。横梁两端还装有可调整天平空载平衡位置的平衡螺母。吊挂系统包括小吊环,挂盘架和秤盘。挂盘架吊挂在小吊环吊钩上,两把边刀分别通过小吊环承受秤盘砝码和被称物的重力。底座装有两个调整天平水平的螺旋调整脚,底座上面还安置有水准器以显示天平水平度。调整水平是为避免天平不水平而产生称量误差。制动装置主要由开关旋钮、开关轴和偏心凸轮(或连杆)组成。转动旋钮使凸轮(或偏心连杆)偏转一定角度,即可使立柱中的升降杆上下移动,通过中刀承将横梁托起或落下,以开启或关闭天平。使用注意事项:1、要放置在水平的地方。2、使用前要使天平左右平衡(游码必须归“0”平衡螺母向相反方向调,使用口诀:左高端,向左调)。3、砝码不能用手拿要用镊子夹取.千万不能把砝码弄湿、弄脏(这样会让砝码腐蚀生锈,砝码质量变大,测量结果不准确),游码也要用镊子拨动。4、被测物体的质量不能超过天平量程或低于天平游码最小刻度。5、潮湿的物体和化学药品不能直接放在天平的盘中。6、称量时注意左物右码(游码示值以左边对齐刻度线为准)。7、称量后要把游码归零,砝码用镊子放回砝码盒。
那位大侠有相关资料?其中原理是什么?那个最小称样量是如何得来的?
我在预习天平的使用,这里不懂,谢谢
二个分度值的具体含义:
1.d是天平的最小刻度,称为分度值,也可叫作最小读数精度。按规定标准称其为天平实际标尺分度值,以符号“d”来代表。
2.e是天平检定标尺分度值,即检定时所用的分度值。检定时用的分度值和天平实际标尺分度值d不同,它不和d值一样是固定不变的,而是需要根据人为规定变化的值。可以规定e=5d,也可以规定e=10d,或者e=2d均可成立,只要不违反国家计量检定规程的规定就可以。
电子天平实际标尺分度值d是表示电子天平的最小精度是多少,检定标尺分度值e是电子天平进行检定时考核技术指标用的。准确的说,看电子天平的最佳精准度不能只看d值,还要看e值。特别是精确称量、科学实验及量值传递等部门在选择精密电子天平如0.01mg电子天平时最好要看检定标尺分度值e。
请问,临床前研究用的电子天平,需要符合GMP要求吗?需要3Q认证吗?相关数据用于申报临床试验的,谢谢
1251分析天平称重提到:电子分析天平有基于所用负载的内部校准系统。此校准适用于当前的环境温度。
<41>砝码与天平里面提到:2级砝码用于内置砝码的分析天平的校准工作,以及用于日常分析工作的实验室砝码。
但是看到一份培训资料,说美国fda不认可电子天平的自校系统的校验。
希望了解的战友执教,天平的自校和外置砝码校验是否都被fda接受。
谢谢
