SOP for Verification of System Suitability Test

SOP for Verification of System Suitability Test
Standard operating procedure to verify system suitability software results Vs manually of the high Performance liquid chromatography for result   accuracy.

 1.0 OBJECTIVE
To Verify system suitability values manually v/s software.

 2.0 SCOPE
This procedure is applicable to verify system suitability software results Vs manually of the high-performance liquid chromatography.

 3.0 RESPONSIBILITY
3.1 Doing: Technical Assistant
3.2 Checking: Executive/ Manager
4.0 ACCOUNTABILITY
Head of the Department

 5.0 PROCEDURE
5.1 Frequency: Once in 6 months.
5.2 Operate the instrument as per respective standard operating procedure of HPLC.
5.3 Prepare the mobile phase consisting of 70% methanol. : 30 % of water.
5.4 Prepare a mixture of 0.1 % Benzene and 0.1% Toluene in methanol.
5.5 Set flow rate at 1.0 ml/min.
5.6 Allow the system to be saturated with mobile phase for at least 15 minutes before injecting the test sample.
5.7 Record the area and retention time of both Benzene and Toluene in methanol.
5.8 Calculate the system suitability parameters with the help of software such as resolution, tailing factor and theoretical plate.
5.9 Now calculate the tailing factor, resolution and theoretical plate manually by following formula:
Theoretical Plate : N = 16 (t/w)2

 Where t = R.T of the component
w = width of the component
Resolution : 2(t2 – t1)/ w1 + w2
Where t1 = R.T of Ist components
t2 = R.T of IInd components
w1 = Width of Ist components
w2 = Width of IInd component
Tailing : T = w/2f
Where w = width of peak
f = width of half peak at 5 % height
The performance of software of the instrument is satisfactory if the all the parameters of the system suitability test are within the acceptance criteria.

Name of software :___________
1. Resolution :
As per software = _________________

                                   2 (t2 – t1)
By manually = R = ------------------
                                     w1 + w2

                      = ----------------- ( +/- 10 %)

 2. Tailing :
As per software = ________________

 By manually   =   T   = w/2f
                       = ------------------------( +/- 10%)

 3) Theoretical Plate :
As per software =______________

By manually = N = 16 (t/w)2
= ------------------------ ( +/- 10%)

 Remarks: Comply/Does not comply
Acceptance criteria : Difference should be within +/- 10.0 %

 6.0 ABBREVIATION

Checklist for Audit in Sterile Area

Checklist for Audit in Sterile Area Checklist to verify the sterile manufacturing area before the audit. 1. Is there any SOP giving details for activity/ movement in the sterile area. 2. Verify the suitability of system for sanitization of hands. 3. Is there the SOP on entry-exit; gowning and de-gowning into the critical area available? 4. Verify the availability of following records:  Air pressure differential  Particulate monitoring  Temperature  Humidity  Microbiological monitoring by settle plate 5. Are these records available and maintained as per SOPs? 6. Check the above mentioned individual records. Are the entries within specifications mentioned in SOP/ MTPs. 7. Is the controlled copy of MTP pertaining to monitoring by settle plate available to plant person? 8. Are the location for settle plates identified and the chart/ layout available with plant? 9. Are the following areas monitored for parameters mentioned in step 4:  Air-lock to the critical ar...

Blow Fill Seal (BFS) and Form Fill Seal (FFS) Technology in Sterile Manufacturing

Blow Fill Seal (BFS) and Form Fill Seal (FFS) Technology in Sterile Manufacturing Know about sterile pharmaceutical production using Blow Fill Seal (BFS) and Form Fill Seal (FFS) technology. Both of these techniques are used to manufacture  sterile pharmaceutical products   as parenteral (LVP & SVP), infusions, ophthalmic and inhalation products. These are automated techniques to prepare sterile products. The basic concept of the  FFS   and BFS is to reduce the  contamination   by forming the container, filling and sealing in a closed sterile chamber of the machine. There is no personnel intervention to reduce the chances of the contamination during the manufacturing of sterile products. It gives more production at very low operational cost with the high assurance of  sterility . Blow fill seal technology is widely used and accepted by the various pharmaceutical regulatory authorities as US-FDA and MHRA. The system is being used for over 30 years a...
