How To Query A Dbo.file Of User-defined Database That Has The Nvarch Type In A Column?

Hi all,
In my SQL Server Management Studio Express, I have the following Database "ChemAveRpd", Table "dbo.LabTests", and Content of the Table:
dbo.LabTests Column_name Type Length Prec Scale
AnalyteID int 4 10 0 (Primary Key)
AnalyteName nvarch 510
CasNumber nvarch 510
Result numeric 5 8 2
Unit nvarch 510
SampleID int 4 10 0 (Foreign Key)

AnalyteID AnalyteName CasNumber Result Unit SampleID
1 Acetone 123-456-9 134.0 ug/L 1
2 Bezene 666-12-8 2.0 ug/L 1
3 Cobalt 421-008-7 10.0 ug/L 1
4 Acetone 123-456-9 201.0 ug/Kg 2
5 Bezene 666-12-8 1.0 ug/Kg 2
6 Cobalt 421-008-7 22.0 ug/Kg 2
7 Acetone 123-456-9 357.0 ug/L 3
8 Bezene 666-12-8 9.0 ug/L 3
9 Cobalt 421-008-7 56.0 ug/L 3


When I ran the following T-SQL code:
USE ChemAveRpd

GO

SELECT *

FROM dbo.LabTests as LabResults

Where AnalyteName = Acetone

GO


I got the following error:

Msg 207, Level 16, State 1, Line 3

Invalid column name 'Acetone'.

Please help and tell me what right syntax I should write for [Where AnalyteName = Acetone] to generate a listing of LabResults for Acetone.

Thanks in advance,
Scott Chang
