Physitemps original Thermes high accuracy ISA based data acquisition system has been redesigned to create a more versatile USB model. The new system requires no internal connections to your computer and simply connects via an external USB port on your laptop or desktop computer. Two versions of the data acquisition system are available. The standard version, THERMES USB, is connected to your computer USB port. The wireless version - THERMES USB WFI, can be either directly connected to a USB port or, with the included wireless receiver, positioned up to 100 feet from the host computer.Each unit will accommodate up to 7 type T thermocouple sensors and multiple Thermes units may be connected to the same computer for more thermocouple inputs. A high accuracy electronic cold junction compensation circuit maintains typical system accuracy of ±0.2°C over an ambient temperature range of 15 to 35°C. Individual offsets may be added to each input in software to facilitate individual calibration of each channel. The THERMES USB WFI is a Type T Thermocouple data acquisition system with asecure 2.4GHz wireless link to its host computer. Specifications for the device are thesame as the THERMES USB except for its wireless capability. The THERMES USBWFI includes a wireless receiver that is connected to the host computer via a USBport. All communications between the host computer and THERMES pass throughthis device. The THERMES USB WFI may be connected directly to the host computervia a standard USB port (from which it also draws its power) or operated remotelyfrom the BP-1 battery pack. A wall mounting USB power supply is also providedwith THERMES USB WFI.
OPT-1 Optical Link A 10 meter optical cable is available with built in transmitter and receiver to allow the THERMES USB to be operated infull optical isolation from the host computer. A medical grade isolated power supply is provided to power the opticaltransmitter and THERMES data acquisition system when used with this cable. Alternatively, a rechargeable Lithium Ionbattery pack, the BP-1, is available to maintain the THERMES-USB or THERMES- USB WFI totally isolated from theAC supply.
BP-1 Li-Ion Battery Pack The model BP-1 Li-Ion battery pack is designed for use with the THERMES USB and THERMES USB WFI Type T temperature data acquisition systems. It allows the data acquisition system to be operated for up to 100 hours continuously without any additional power source. The BP-1 provides either 16V, 19V or 5V DC output to run either the THERMES or a laptop for an extended period of time. The power supply has a capacity of 130 watt hours allowing the THERMES to operate for up to 100 hours continuously. Operating time with a laptop will vary from 3-4 hours in addition to the laptops fully charged normal running time. The BP-1 may also be used with the OPT-1, opto-isolator cable with the adaptor cable provided. A charge level indicator comprising four LEDs indicate remaining battery life.
Operating SoftwareFor customers who already have Labview or Dasylab no additional software is necessary. Recommended operating software is Dasylab Lite version 9.01. The Lite version provides all the necessary functions to display and store temperature data in digital and graphical formats in real time. Users may customize the display to suit their particular application. The Dasylab Basic version provides additional features for data manipulation and statistical analysis.

求助各位前辈，我最近在合成的化合物水溶性很好，非常好，以至于可以随便溶解在水里，它的六氟磷酸盐也可以随意溶解在水里（大于50uM），细胞成像实验显示它根本进不去细胞，求问有没有啥方法包裹一下让它进去？我搜了一下文献，感觉多数是把脂溶性特别好的东西包裹一下弄进去的，也许是搜索姿势不对没找到我需要的答案，**点拨啊！！！
求助各位大神，现在想购买小分子数据库，求大神推荐。
我知道的免费的数据库有zinc
求推荐哪家公司或者研究所的小分子数据库可以购买，十分感谢！！！！！！
求助大家，小分子药物最新专利申请情况跟踪，之前听别人说可以在一个网站可以导出这个信息。
不知哪位大侠知道，告知一下，不胜感激！
就是蛋白质分子的小片断
是氨基酸形成的
一、首先你要明白肽是什么...........................肽是氨基酸通过酰胺键结合而成的东西.........
二、你要明白氨基酸是什么..........................氨基酸是构成蛋白质的基本单位，多种氨基酸结合为长肽链，几条长肽链再盘旋就形成了蛋白质......................
三、关于小分子肽、短肽、多肽、寡肽.......其实都是肽.......区别只是由多少个氨基酸构成而已............
所以，你的问题可以很粗暴地理解为“蛋白质对人体有没有副作用”.......
如果你营养足够的情况下，再补充这个，会导致营养过剩，从而加重身体代谢的负荷............类似就是这样子的了...........小分子肽，一般现在用于化妆品上比较多（一ye子.植物肽面膜就是这个）.......小分子肽（可以简单理解为纳米胶原蛋白），这比蛋白质（也可以粗暴理解为胶原蛋白）更加容易吸收......而用在食品上，要视乎是何种小分子肽了.....大豆肽、花生肽、大米肽....不同的肽有不同的功效.......主要可以改善风味、改善吸收、增强胃肠道功能等等.......
有机的是有机化合物的简称,它指的是含碳化合物.
但是,有四大类常见物质一般不作为有机物处理：
1、碳的氧化物,如CO和CO2.
2、碳酸及其盐,如CaCO3.
3、金属碳化物,如CaC2.
4、拟卤素及其化合物,如(CN)2与KSCN.
水的化学式为H2O,它不含有碳元素,故不是有机物.
但若所描述的水不是化学意义的水,而是自然界存在的天然水,那么,水中会溶有一定量的有机物.
