Elemental Analysis

Elemental Analysis belongs to one of our earliest and most often requested services. It serves two purposes:

• To provide for pure materials elemental composition for which an empirical formula can be derived.
• To assess the purity of pharmaceutical preparations, chemicals, and high quality solvents.

CH/CHN/O

Our experienced staff uses the Perkin Elmer 2400 CHN analyzer to provide accurate and fast results.

Most samples are analyzed on the day they are received.

Sample requirement: 3.0 mg (often 1.0 mg is sufficient).

Reporting limits: from detection limit of 0.02% to range of 100%.

S-F-Cl-Br-I-P

Generally Titration, Ion Chromatography and specific element methods are used for best micro analytical results.

To obtain optimized analytical methods for best accuracy, various analytical techniques are used to address a large variety of cross-interferences and concentration levels.

Sample requirement: 5-10 mg/element (assuming that 5 % of the element is present).

Reporting limits: from detection limit of 0.02% to range of 100%, depending on the method used.

KF

We use the coulometric water determination according to the Karl Fisher method (KF-H2O). The detection limit is 10 mg to high % levels.

Sample requirement: 3-10 mg.

Reporting limits: from range of 0.1 % to high percent level.

Ash

Ash can be defined as non-combustible inorganic residue, Residue on Ignition (ROI).

Sulfated ash can also be determined.

Sample requirement: 10 mg.

Reporting limits: as low as 0.1 % ash reported.
