ACD/Labs databases and SPECTRUS

ACD/Spectrus DB Enterprise fills the gap in many

cheminformatics and business informatics architectures

It is a system that can store and use the connection

between raw analytical chemistry data, its scientific

interpretation and the decisions driven by that analysis.

Tested in laboratories worldwide, this unique database

creates a collaborative project environment that in

addition to storing data for intellectual property rights

preservation, also offers a searchable repository with

access to the knowledge gained by individual scientists

and groups, to benefit the whole organization for years

to come.

8



Spectrus DB Enterprise is a multi-technique, multi-vendor spectral interpretation

tool and is a redevelopment of tried and tested knowledge management software

(ACD/ChemFolder Enterprise and ACD/SpecManager), with enhancements to

meet the needs of R&D organizations and IT professionals:

Instantly collect disparate information from multiple analytical instruments

running numerous techniques into a single homogeneous environment;

Establish and visualise a chemically intelligent connection between chemical

structures, reactions and related analytical data and chemical information;

Capture the human interpretation of data and knowledge gained in the

decision-making process;

Search and find legacy knowledge, by an unprecedented number of chemical

and spectral parameters;

Add optional automated processing and interpretation, for higher productivity;

Sample tracking and visualisation options to fit workflows;

Integrate with existing systems to enhance their capabilities and gain

maximum benefit from your investments.

Types of Databases

Local and Remote

Spectrum databases

currently called ‘*.nd9’

SPECTRUS DB Enterprise

currently ‘*.cfd’

Analytical interpretation

e.g. ‘*.NMRUDB’ for C+H Predictors

PostgreS(QL) or Oracle Object-relational Database Management

Systems.

Links seamlessly to documents e.g. Word, Excel, Powerpoint

Links to other databases, e.g. Access, Claros and allows cross

database search and retrieval.

10

Workflow – information in databases

Organisation of staff – team structures

Research programs – plans, progress, reviews

Time lines

Safety – risk assessments, near misses, incident and

accident reports

Purchasing – starting materials, storage points, amounts,

life times, products, quantities, destination, archive.

Experiment logging, electronic lab notebooks, analytical

data capture, interpretation, data classification and

knowledge building.

Reporting – experimental results, monthly reports, annual

reviews, publications, patents

New knowledge gained, resulting rules defined

22


Future developments

Web based software handling and searching

Unlimited database sizes

Remote viewing and interrogation over the web.
