When analyzing samples from a complex matrix such as soil, tissue,
serum/plasma, whole blood, and other sources, note that the matrix
components can adversely affect LC/MS results, enhancing or suppressing
ionization. To minimize these matrix effects, adopt the following measures:
• Prior to the instrumental analysis, use appropriate sample
pretreatment such as protein precipitation, liquid/liquid extraction
(LLE), or solid phase extraction (SPE) to remove matrix interferences.
• Whenever possible, verify method accuracy and precision using
matrix-matched calibrators and QC samples.
• Use one or more internal standard compounds, preferably isotopically
labeled analytes.
EMC considerations
Canada spectrum management emissions notice
This class A digital product apparatus complies with Canadian ICES-001.
Cet appareil numérique de la classe A est conforme à la norme NMB-001.
ISM Classification: ISM Group 1 Class A
This classification has been assigned in accordance with CISPR 11 Industrial
Scientific and Medical, (ISM) instrument requirements. Group 1 products
apply to intentionally generated and/or used conductively coupled
radio-frequency energy that is necessary for the internal functioning of the
equipment. Class A products are suitable for use in all establishments other
than residential locations and those directly connected to a low voltage power
supply network supplying a building for domestic purposes.
There may be potential difficulties in ensuring electromagnetic compatibility
in other environments due to conducted as well as radiated disturbances.
Do not use the equipment in close proximity to sources of strong
electromagnetic radiation (for example, unshielded intentional RF sources), as
these may interfere with the equipment’s proper operation.
This equipment complies with the emission and immunity requirements
described in the relevant parts of IEC/EN 61326: Electrical equipment for
measurement, control and laboratory use — EMC requirements.
