爱丁堡FLS980和HORIBA FL-3荧光光谱仪哪个好？
|
||||
|
实验室想购买荧光光谱仪，需要满足以下要求： 1. 稳态光谱测试 2. 绝对荧光量子效率测试 3. 瞬态光谱测试，即荧光寿命测试 4. 光谱范围：紫外可见近红外 目前调研的仪器有爱丁堡FLS980和HORIBA FL-3可满足要求，不知道有没有同学用过这两款仪器，那个更好一些？或者这两款仪器都有哪些问题？ |

这个我可以告诉你，各有各的优点。 两家都打过交道，我用的是JY的，当年买仪器的时候JY还没有被Horiba收购。为什么爱丁堡在国内卖的比Jy好是有原因的。当初JY为了专心做Raman谱仪（他们的Raman国内占有率很高），就把荧光这一块让天美公司全权代理，后来，天美把爱丁堡收购了，作为两个主流品牌竞争对手，不可能让一家公司做，因此JY把荧光的事务又收了回去自己做，大概也就是13年的事。因此，荧光这一块JY需要重新培养客户，而天美的渠道已经经营多年，短期内更占优势。不过JY目前正加大这一块的人员和力量投入，相信不久还是会形成两强鼎力的局面。仪器本身技术都很成熟，买谁差别不大。关键是售后，我觉得JY的售后比当初和他们打交道时已经好了很多，尤其是把一个技术很过硬的老外工程师常驻中国后，目前还没遇到他们解决不了的问题。OPO是个不错的新东西，但是据说技术还不是特别成熟，我周围的两家买了OPO就经常出问题，看来好东西还需逐步完善。 |

我糊涂了，难道搞研究和测试仪器有什么区别吗，测试的目的不就是研究吗？难道JY的不是工具？ 可否聊聊JY的具体优势在哪里，比如说JY能做的爱丁堡不能做，或者仪器设计方面更优，或者信噪比更高，或者数据可信度更高? 单纯从市场上来看，不能完全反应出来的，毕竟JY的仪器多少年了，发的文章多也很正常啊。 后来又调研了下，JY市场占有率确实高，但是他的产品种类比爱丁堡要多，单纯到大荧光上面，优势就没那么强了 总的调研下来，最重要的部件之一，检测器都是同一家公司生产的，其他的部件，具体参数两家有出入，但是爱丁堡的绝对没明显劣势 售后方面，有人反映JY很贵的，具体爱丁堡的怎么样，不知道有没有人能够说说 |
