Bio-Rad宣布推出新版本的KnowItAll軟件及譜圖庫

Bio-Rad宣布推出其屢獲殊榮的KnowItAll?光譜軟件9.0新版本，此版本將對光譜庫的光譜范圍和分辨率進行全新定義。

KnowItAll 9.0允許客戶將光譜以原始的范圍和分辨力存儲在自建庫中。用戶能夠更好的管理他們的原始數據，更精確地和標準譜圖對照。

“計算機技術的進步取消了磁盤空間和計算速度的約束，使得光譜對比計算能取得如此重大進展。” Bio-Rad信息部總經理Gregory M. Banik博士解釋，“由于光譜分辨率對于檢索結果有著顯著的影響，去除對光譜范圍和分辨率的限制對檢索或存儲數據非常重要。隨著KnowItAll 9.0版本的發布，研究人員可以保存完整的原始數據。他們還可以使用遵守由Bio-Rad公司和美國材料試驗學會標準光譜檢索專家制定的最佳步驟的檢索軟件。”

　KnowItAll 9.0版本的附加功能包括：

1、多元多層次地管理多種分析技術的屬性

2、用戶數據庫創建程序大大簡化

3、新的化合物結構式繪圖工具符合IUPAC畫圖指南

4、高分辨HaveItAll? IR、NIR、拉曼數據庫光譜

5、增加HaveItAll IR, UV-Vis和 NMR數據庫數量

關于光譜檢索

在一些應用領域，研究人員使用光譜檢索軟件對合成材料的組成成分進行識別和鑒定。首先，通過精密設備測量物質產生光譜圖，圖中一系列的波峰和波谷表示特定的樣品材料的性質。然后將譜圖與標準譜圖相比較。如果找到匹配的光譜，就可以對材料進行識別。Bio-Rad公司的KnowItAll提供了這一工具以及世界上最精、最廣泛的譜圖收藏，幫助用戶進行這種類分析。

關于KnowItAll 信息軟件

Bio-Rad公司的KnowItAll 信息系統結合了化學軟件和數據庫，從而能夠為科學研究人員提供多種工具，包括數據庫建立和管理、檢索、分析、結構式繪制和分析報告等。公司的獲獎產品KnowItAll信息系統能夠為紅外光譜、拉曼光譜、近紅外光譜、核磁共振、質譜、紫外-可見光譜、色譜、化學計量學和代謝組學等提供靈活和可擴展的解決方案。

Bio-Rad公司信息部（www.informatics.bio-rad.com）專門為光譜、化學、化學計量學以及代謝組學等科學領域提供軟件和數據庫解決方案。Bio-Rad公司以出版各種譜庫和數據庫而聞名，擁有經過充分驗，包含超過140萬種譜圖的譜庫。

Bio-Rad Announces Advances in Spectral Searching and Database Building in Its KnowItAll Software

Bio-Rad has announced an unlimited spectral range and resolution feature in version 9.0 of its award-winning KnowItAll? spectroscopy software.

KnowItAll 9.0 allows users to store spectra in a user database at the precise range and resolution at which each spectrum was measured rather than being forced to conform to a fixed range and resolution for the entire database. As a result, users have more control over their data and can perform more accurate spectral searches that compare experimental spectra to reference databases.

"Technological advances have changed disk space and computational time limitations of computer search methods, making possible major advances in spectroscopic computing," explained Gregory M. Banik, Ph.D., General Manager, Bio-Rad Informatics. "Removing constraints on spectral data is critical to those who perform spectral searches or store spectral data, since altering an original spectrum’s resolution has a significant impact on search results. With KnowItAll 9.0, researchers can preserve the integrity of their spectral databases. In addition, they have access to search software that follows best practices defined by the most recent research conducted by spectral search experts at Bio-Rad Laboratories as well as American Society for Testing and Materials standards."

Additional features in the KnowItAll 9.0 release include:

• 　　Independent management of properties from multiple analytical techniques in user databases
• 　　User database creation simplified
• 　　New structure drawing tools to comply with IUPAC structure drawing guidelines
• 　　Higher resolution spectra in HaveItAll? IR, NIR, Raman database subscriptions
• 　　Spectra added to HaveItAll IR, UV-Vis, and NMR database subscriptions

About Spectral Searching

Researchers use spectral search software to identify unknown substances and verify the composition of synthesized materials in a number of applications and industries. First, precision instruments measure a substance and produce a spectrum, which is expressed as a graph showing a series of peaks and valleys that is specific to the sample material. That spectrum is then compared with a database of the measured spectra of known substances. If a matching spectrum is found, the material in question can be identified. Bio-Rad’s KnowItAll solutions provide search software tools, as well as the world’s most extensive collection of reference spectra used in this type of analysis.
