Bio-Rad宣布推出新版本的KnowItAll软件及谱图库

Bio-Rad宣布推出其屡获殊荣的KnowItAll®光谱软件9.0新版本，此版本将对光谱库的光谱范围和分辨率进行全新定义。

KnowItAll 9.0允许客户将光谱以原始的范围和分辨力存储在自建库中。用户能够更好的管理他们的原始数据，更精确地和标准谱图对照。

“计算机技术的进步取消了磁盘空间和计算速度的约束，使得光谱对比计算能取得如此重大进展。” Bio-Rad信息部总经理Gregory M. Banik博士解释，“由于光谱分辨率对于检索结果有着显著的影响，去除对光谱范围和分辨率的限制对检索或存储数据非常重要。随着KnowItAll 9.0版本的发布，研究人员可以保存完整的原始数据。他们还可以使用遵守由Bio-Rad公司和美国材料试验学会标准光谱检索专家制定的最佳步骤的检索软件。”

　KnowItAll 9.0版本的附加功能包括：

1、多元多层次地管理多种分析技术的属性

2、用户数据库创建程序大大简化

3、新的化合物结构式绘图工具符合IUPAC画图指南

4、高分辨HaveItAll® IR、NIR、拉曼数据库光谱

5、增加HaveItAll IR, UV-Vis和 NMR数据库数量

关于光谱检索

在一些应用领域，研究人员使用光谱检索软件对合成材料的组成成分进行识别和鉴定。首先，通过精密设备测量物质产生光谱图，图中一系列的波峰和波谷表示特定的样品材料的性质。然后将谱图与标准谱图相比较。如果找到匹配的光谱，就可以对材料进行识别。Bio-Rad公司的KnowItAll提供了这一工具以及世界上最精、最广泛的谱图收藏，帮助用户进行这种类分析。

关于KnowItAll 信息软件

Bio-Rad公司的KnowItAll 信息系统结合了化学软件和数据库，从而能够为科学研究人员提供多种工具，包括数据库建立和管理、检索、分析、结构式绘制和分析报告等。公司的获奖产品KnowItAll信息系统能够为红外光谱、拉曼光谱、近红外光谱、核磁共振、质谱、紫外-可见光谱、色谱、化学计量学和代谢组学等提供灵活和可扩展的解决方案。

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.
