Abstract

Objective:
This study describes the
development and validation of
a gas chromatography–flame
ionization detection (GC–FID)
method for the quantitative heroin
(diacetylmorphine), morphine,
codeine (3-methylmorphine) and
6-monoacetylmorphine (6 MAM) in
narcotics.
Methods:
In our study, GC/FID Agilent 6890N
(DB-5: 10,0m x 100 µm x 0,17
µm) with Chemstation software
and 5% phenylmethylpolysiloxane
non polar analytic colon
(max 325 °C) was used for
the analyses. Standards and
reagents were Dichloromethaneisopropylalcohol mixture (1:
1), Methanol, HeroinHCl.H2O,
CodeineHCI, MorphineHCI,
6-MonoacetylmorphineHCI,
Paracetamol, caffeine and
n-docosane which were used as
reference standard and internal
standard. Carrier gas was Helium.
Injection temperature (T) was
280 ˚C, injection volume was 1 µl.
Repeatability study was evaluated
using 4 operators. Reproducibility
study was evaluated using 3
operators during 29 days.
Results:
The method is linear over the
range (0.01-2.00mg mL-1) for
heroin, (0,008-2 mg L-1) for
codeine, (0,005-2 mg mL-1) for
6-monoacetylmorphine and (0.015-
0,75mg mL-1) for morphine in the
study. Correlation coefficients
vary between 0.997 and 0.999 are
detected.
Conclusion:
The increases in demanding of
human rights, in getting prevalent
of special insurances make
it obligatory to perform total
quality principles particularly for
forensic disciplines. Reliability
and credibility are also found very
important by the courts. For this
reason validation and continual
reclamation of methods that have
been used in forensic laboratories
is getting very important.
