Introduction 1 Introduction 1.1 General ™ This manual describes Autosampler A-905 for ÄKTA ™ Autosampler A-905 for Ettan . They are automated sampling injectors for use in ÄKTA and Ettan liquid chromatography systems. The autosampler features: • Sample injection volumes as follows: •...
Introduction 1.2 Safety • The instrument is designed for indoor use only. • Do not use in a dusty atmosphere or close to spraying water. • Do not block the air inlet and outlet of the unit. WARNING! Always disconnect the power supply before attempting to replace any item on the instrument.
Installation 2 Installation 2.1 Unpacking Unpack the instrument and check the items against the supplied packing list. Inspect the items for obvious damage that may have occurred during transportation. Keep all packing materials if onward transport of the instrument is expected.
Installation 2.2 Locating the A-905 The A-905 needs approximately 28 cm of bench space and a mains connection of 220-240 V or 100-120 V, 50/60 Hz, preferably taken from the system base platform. Make sure that none of the ventilation holes are blocked. Blockage of the ventilation holes can cause malfunctioning of the A-905 Autosampler or even damage the electronics.
Installation 2.3 Power connections Before connecting the mains cord to your separation unit, check that the voltage setting of the A-905 matches the local mains supply voltage and main fuses. Use only a supply appliance with protective grounding. If the indicated voltage is not correct, select the proper voltage by removing, inverting, and then re-inserting the voltage selector- cartridge.

Maintenance 4.1.3 Maintenance (Autosampler A-905 for ÄKTA) With normal use, the valve will give many tens of thousands of cycles of trouble-free operation. The main cause of early failure, which is seen as a leak in the valve, is abrasive particles in the sample and/or mobile phase scratching the rotor seal.
Page 31
Maintenance 4.1.4 Maintenance (Autosampler A-905 for Ettan) With normal use, the valve will give many tens of thousands of cycles of trouble-free operation. The main cause of early failure, which is seen as a leak in the valve, is abrasive particles in the sample and/or mobile phase scratching the rotor surface.
Page 32
Maintenance 4.1.5 Operating suggestions CAUTION! Never operate the injection valve when it is dry. This will reduce the lifetime of the injection valve and probably cause malfunction. CAUTION! Never leave the A-905 for more than one day with buffer solution in the tubings. Rinse the A-905 with distilled water prior to long stops, and fill the tubing with 20% ethanol.
Maintenance 4.2 Needle and tubing The A-905 has separate needles for puncturing and sampling; the air needle, which punctures the septum of the vial and provides the headspace pressure in the vial, and the sample needle for transporting the sample from the vial into the loop of the valve. The sample needle enters a vial as follows: Fig.
Maintenance 4.3 Syringe, sample loop and buffer tubing combinations Four sizes of dispenser syringes are available: 100, 250, 500 and 1000 µl. 4.3.1 Injection volumes Table 4-1 shows the injection volume ranges that are available for the the different injection modes.

Page 35
Maintenance 4.3.3 Flush volumes The recommended minimum flush volumes are 30 µl (ÄKTA) and 10 µl (Ettan). The default values for the flush volume are 40 µl (ÄKTA) and 10 µl (Ettan). The recommended flush volume with an air segment is 35 µl. Note: When an air segment is selected from the InjectionPickup_905 instruction in...
Page 36
Maintenance 4.3.5 Injection volumes smaller than 20 µl Use a 100 µl syringe and a 5 µl sample needle to obtain maximum reproducibility and accuracy. Use a 20 µl sample loop to avoid loss of accuracy due to expansion of the loop content when switching from inject to load position prior to sample loading.
Page 37
Maintenance 4.3.7 For volumes larger than 200 µl Select the syringe size according to the recommendation below: Syringe volume > 2 × injection volume. Injection volumes larger than 500 µl are possible, but the sample might contaminate the syringe. Program sufficient wash after use! Follow the recommendations in the table below for choosing the appropriate buffer tubing and sample loop: Syringe...
Maintenance 4.4 Replacing the sample needle To replace the sample needle, proceed as follows: 1 Use the AutosamplerControl_905:NeedleFront_905 command in to move the needle to the Manual:Flowpath front. Rheodyne nut 2 Loosen the needle connection nut (Male nut M6) that and ferrule fixes the sample needle.
Maintenance 4.5 Syringe Autosampler A–905 is factory-equipped with a 1 ml syringe (ÄKTA) or a 100 µl syringe (Ettan). 250 µl and 500 µl syringes can also be used. To install another syringe, proceed as follows: Note: Do not disconnect the power supply of the A–905. It is needed to move the syringe.
