美國月旭Welch公司（Welch Material，Inc.）   www.welchmat.com
月旭材料科技（上海）有限公司（簡稱上海月旭）專注于研發(fā)、生產(chǎn)和銷售色譜分離材料并為廣大的色譜使用者提供完整的色譜分離純化解決方案。公司于2003年在美國馬里蘭州和上海張江同時注冊成立，美國注冊為 Welch Materials, Inc.。 
公司的主要創(chuàng)始人分別畢業(yè)于復(fù)旦、 北大和中國科大，留學美國加州大學柏克利分校（UC Berkeley）和麻省理工學院 (MIT)等知名學府并得到化學專業(yè)博士學位。他們在創(chuàng)辦上海月旭之前都曾在美國高科技領(lǐng)域的大公司任職10多年。具有相似經(jīng)歷的他們把在國外學到的先進技術(shù)和管理經(jīng)驗帶回國內(nèi)，并充分利用中美兩國的優(yōu)勢資源，致力于為中國及世界的食品、制藥、環(huán)保及化工等行業(yè)提供最優(yōu)化的色譜分離純化解決方案。 
上海月旭強大的研發(fā)和技術(shù)團隊里有三名海歸博士和多名國內(nèi)清華、北大和復(fù)旦等名校的畢業(yè)生。公司在色譜技術(shù)研究、產(chǎn)品開發(fā)、市場營銷等方面已經(jīng)積累了豐富的經(jīng)驗和諸多的成功案例。 
憑借強大的技術(shù)研發(fā)能力和銷售團隊，上海月旭目前已成功推出并實現(xiàn)規(guī)模銷售的有Ultimate® （極限柱）、Welchrom® （優(yōu)譜柱）、XtimateTM（超限柱）和TopsilTM （拓譜柱）四大系列色譜柱、SPE固相萃取小柱和色譜填料等產(chǎn)品。上海月旭在色譜領(lǐng)域已擁有多項核心技術(shù)，包括國家發(fā)明專利技術(shù)和屬于商業(yè)秘密性質(zhì)的關(guān)鍵技術(shù)，在小顆粒硅膠表面修飾處理、固定相雙封尾鍵合、重現(xiàn)性控制的SmoothPack技術(shù)和填料的高pH耐受性處理工藝等方面取得了很多創(chuàng)新性的成果。上海月旭是上海市高新技術(shù)企業(yè)，并兩次獲得國家科技部的科技型中小企業(yè)創(chuàng)新基金。 
上海月旭在上海設(shè)有應(yīng)用實驗中心，在北京、天津、廣州等地設(shè)有14個辦事處。公司的中國客戶包括清華大學、復(fù)旦大學、北京大學、沈陽藥科大學、中國藥科大學、同濟大學、上海中醫(yī)藥大學及湖南大學等全國30多所知名院校實驗室；上海市食品藥品檢驗所、中國藥品生物制品檢定所、上海市疾控中心、廣東出入境檢驗檢疫局等各省市藥檢和疾控系統(tǒng)第三方檢測機構(gòu)；海正制藥、華海制藥、哈藥集團、修正制藥等幾百家國內(nèi)知名藥企；圣元乳業(yè)、水井坊、王老吉等多家知名食品飲料企業(yè)。憑借前瞻性的研發(fā)和良好的產(chǎn)品性能，月旭產(chǎn)品遠銷美國、加拿大、印度、巴西、阿根廷等國家。 
超“月”極限，“旭”寫輝煌——上海月旭將始終堅持“極限的性能、合理的價格、最好的服務(wù)”的經(jīng)營理念，并持之以恒地做出努力把自己建設(shè)成為國內(nèi)領(lǐng)先、國際前沿的色譜分離純化供應(yīng)商。

Welch Materials Inc. is a US-based manufacturer of hi-tech materials, with a wholly owned subsidiary, Yue Xu Materials (Shanghai) Inc. in China. Welch Materials, Inc. was founded by several Ph.D. scientists from top universities such as MIT, University of California at Berkeley. Welch Materials, Inc. focuses on research and development of value-added hi-tech consumable products for life science, pharmaceutical, chemical, environmental, and semiconductor industries.
We manufacture next generation WelchromTM XB series HPLC columns (which are also sold under UltimateTM XB series brand in China) for chemists in the fields of pharmaceuticals, food, drug control, environmental, agrochemicals, cosmetics and academic labs. Our WelchromTM HPLC columns are made from spherical, totally porous, and ultra high purity (>99.999%) type B silica particles. Our proprietary surface modification treatment before bonding generates a very smooth and uniform surface with less acidic surface silanols. We offer a full line of phases including XB-C18, AQ-C18, XB-C8, XB-Phenyl, and XB-CN to provide a wide range of selectivities. These phases were developed using state-of-the-art bonding chemistry technology to provide unique performance characteristics to enable the most demanding separations. All phases are fully end-capped by proprietary techniques to ensure excellent peak shapes and long lifetime. All bonding, end-capping and packing processes are optimized and well-controlled to achieve maximum efficiency, excellent batch-to-batch and column-to-column reproducibility, and longer lifetime. WelchromTM HPLC columns provide the ultimate performance in peak shape, efficiency and resolution. Through continuous innovation, Welch Materials offers customers the best tools and solutions for separation, purification, and analysis of organic and bioorganic compounds.
