愛丁堡FLS980和HORIBA FL-3熒光光譜儀哪個(gè)好?
|
||||
|
實(shí)驗(yàn)室想購買熒光光譜儀,需要滿足以下要求: 1. 穩(wěn)態(tài)光譜測試 2. 絕對(duì)熒光量子效率測試 3. 瞬態(tài)光譜測試,即熒光壽命測試 4. 光譜范圍:紫外可見近紅外 目前調(diào)研的儀器有愛丁堡FLS980和HORIBA FL-3可滿足要求,不知道有沒有同學(xué)用過這兩款儀器,那個(gè)更好一些?或者這兩款儀器都有哪些問題? |

這個(gè)我可以告訴你,各有各的優(yōu)點(diǎn)。 兩家都打過交道,我用的是JY的,當(dāng)年買儀器的時(shí)候JY還沒有被Horiba收購。為什么愛丁堡在國內(nèi)賣的比Jy好是有原因的。當(dāng)初JY為了專心做Raman譜儀(他們的Raman國內(nèi)占有率很高),就把熒光這一塊讓天美公司全權(quán)代理,后來,天美把愛丁堡收購了,作為兩個(gè)主流品牌競爭對(duì)手,不可能讓一家公司做,因此JY把熒光的事務(wù)又收了回去自己做,大概也就是13年的事。因此,熒光這一塊JY需要重新培養(yǎng)客戶,而天美的渠道已經(jīng)經(jīng)營多年,短期內(nèi)更占優(yōu)勢。不過JY目前正加大這一塊的人員和力量投入,相信不久還是會(huì)形成兩強(qiáng)鼎力的局面。儀器本身技術(shù)都很成熟,買誰差別不大。關(guān)鍵是售后,我覺得JY的售后比當(dāng)初和他們打交道時(shí)已經(jīng)好了很多,尤其是把一個(gè)技術(shù)很過硬的老外工程師常駐中國后,目前還沒遇到他們解決不了的問題。OPO是個(gè)不錯(cuò)的新東西,但是據(jù)說技術(shù)還不是特別成熟,我周圍的兩家買了OPO就經(jīng)常出問題,看來好東西還需逐步完善。 |
| 14樓說的挺對(duì)的 是那會(huì)天美吧JY做臭了 JY 的東西還是挺不錯(cuò)的 售后那會(huì)天美沒跟上說以在國內(nèi)普及率沒有愛丁堡的高 不過現(xiàn)在JY也自己有國內(nèi)新的團(tuán)隊(duì)代理 我感覺他們做的還是挺不錯(cuò)的 我覺得還是JY的比較穩(wěn)定些吧 我們學(xué)校那會(huì)用的就是JY后來到單位用的就是愛丁堡就覺得不太好 也可能是我用習(xí)慣JY的了吧 |

我糊涂了,難道搞研究和測試儀器有什么區(qū)別嗎,測試的目的不就是研究嗎?難道JY的不是工具? 可否聊聊JY的具體優(yōu)勢在哪里,比如說JY能做的愛丁堡不能做,或者儀器設(shè)計(jì)方面更優(yōu),或者信噪比更高,或者數(shù)據(jù)可信度更高? 單純從市場上來看,不能完全反應(yīng)出來的,畢竟JY的儀器多少年了,發(fā)的文章多也很正常啊。 后來又調(diào)研了下,JY市場占有率確實(shí)高,但是他的產(chǎn)品種類比愛丁堡要多,單純到大熒光上面,優(yōu)勢就沒那么強(qiáng)了 總的調(diào)研下來,最重要的部件之一,檢測器都是同一家公司生產(chǎn)的,其他的部件,具體參數(shù)兩家有出入,但是愛丁堡的絕對(duì)沒明顯劣勢 售后方面,有人反映JY很貴的,具體愛丁堡的怎么樣,不知道有沒有人能夠說說 |
