s*****0 发帖数: 244 | 7 请问版上有没有同学,朋友做ion mobility mass spectrometry的,如果在Mike
bowers, David Clemmer, David Russell组学习工作的,能不能留个联系方式。我想一
起合作。
万分感谢! |

x*****9 发帖数: 68 | 12 好像一般测序啥的都用positive mode
因为我的peptides上有磷酸根, 所以想试一下negative ion mode,
mobile phase
A: 100% H2O 0.1% NH4OH,
B: 5% H2O 95 ACN 0.1% NH4OH
自己pack的 C18 capillary column
在一开始就碰到问题,
发现capillary column很容易堵住, 压力狂升, 最后系统shut down
有时候还能在tip上发现一些白色的crystal, 不知道啥东西
希望版上有经验的同学 指点指点 |

b*******g 发帖数: 1309 | 13 not soluble in in ACN?
negtive ion mode generally is not sensitive, and you can detect phosphorylated peptides in positive mode. |

v********g 发帖数: 25 | 14 溶剂和positive ion mode一样,ESI极性换一下就行了,照喷。 |

x**o 发帖数: 134 | 15 I need to do some research on Ion Chromatography. But I didn't involve much
research before in IC and I'd like to do something new or relatively new. I
am hoping to publish something.
We have a dual column (anion and cation) Dionex IC.
Is there anybody in the area? Please shine some lights to me. Many thanks! |

也请推荐几本书吧!
谢谢大家! |

a******u 发帖数: 238 | 18 不懂,也没听说过。
是指利用磁场来聚焦ion? |

OK, at beginnig I agree with you that the complexation may account for the
appreant purple color. But later I did not find any evidence from literature
supporting this supposion.
Moreover, it seems a bit uncommon thinking about complexation in my case...
this is not my ultimate target for sure, but this is a bit unexpected.. |

m*****n 发帖数: 213 | 22 大家好,本人博士在读,希望能够开始积累审稿经验。现在只有一篇Adv. Mater. 被接
收,另外两篇Nat. Nanotechnol.和Nano Lett.都是under review。
希望大家有Nanomaterials,Supercapacitor,Li-ion battery,Solar cell等方向的文章
如果需要审稿请站内信我。我会尽我所能认真仔细地完成审稿工作,感激不尽,谢谢大
家。 |

w********o 发帖数: 10088 | 23 sims有没有可能撞击出来的ion不是单个的,而是两个或者两个以上bond在一起的
比如说,撞出来的是N-N,原子量就是28,但是如果我们原定去寻找Si,sims的detect会把
这个N-N当作Si
有没有这个可能呢,谢谢 |
|
s******n 发帖数: 201 | 24 当然可能,这里ion可以是分子离子也可以是团簇离子。
主要取决于你的靶材。
还有可能出来不是单价态的离子(〉=+2) |
|
w********o 发帖数: 10088 | 25 多谢多谢,是不是说靶材可以提供的ion能量不同,所以有了局限性 |

ion咋了?就当个小破车开开,也不想花太多钱,不好? |
|

话说当年s系列的发动机被谁继承去了?
那可是省油省得我心理暗爽啊~ |

w*******y 发帖数: 60932 | 41 I thought I missed the deal for this deal from Newegg on black Friday.. but
it's back with different combo. On black friday, it was a deal with external
dvd burner.
This one comes with G.SKILL 2GB 200-Pin DDR2 SO-DIMM DDR2 800 (PC2 6400)
Laptop Memory Model F2-6400CL5S-2GBSQ. I personally like this deal better
since I didn't need DVD burner but I'd need new RAM.
