شرایط پلاسما از پیش تعیین شده قدرتمند اسپکترومتر جرمی پلاسما جفت شده القایی ICP-MS
|
Plasma conditions on the 7900 ICP-MS are robust and easily reproduced using the pre-set plasma function within MassHunter — no manual tuning is required. Consistent hardware engineering ensures that operating conditions can be precisely set and consistently applied from day to day and with different operators. Signal suppression for high ionization potential elements such as Be, Zn, As and Cd in 10 vol% HNO3 matrices is typically less than 10% (Plasma mode: General Purpose).

رابط های اسپکتروسکوپی جرمی پلاسما جفت شده القایی ICP-MS
|
|
مخروط نمونه برداری طیف سنجی جرمی پلاسما جفت شده القایی ICP-MS
|
1 mm diameter orifice, Ni-tipped or Pt-tipped (option) with Cu base. Easy access to the interface region for routine maintenance; no tools are required for removal/refitting of sampling cone. The large cone-retaining ring ensures reliable thermal contact and reproducible fitting, even with different operators, giving dependable long-term performance.
|
|
مخروطی اسکیمر اسپکتروفتومتر جرمی پلاسما کوپل شده القایی ICP-MS
|
: 0.45 mm diameter orifice, Ni or Pt-tipped (option). Precisely controlled skimmer tip temperature ensures minimal matrix condensation, providing good tolerance to high matrix samples. Small skimmer orifice reduces matrix contamination of the high vacuum region, reducing maintenance
|
|
لنز یونی اسپکترومتر جرمی پلاسما کوپل شده القایی ICP-MS
|
The ion lens provides high ion transmission (> 1GHz/ ppm sensitivity at <2.5% CeO/Ce) and low backgrounds to deliver superior detection limits. The ion lens design also ensures that fi xed voltages can be used to achieve optimum ion transmission across the mass range.
|
|
لنز خارجی اسپکتروسکوپی جرمی پلاسما کوپل شده القایی ICP-MS
|
Positioned behind the skimmer cone, the extraction lens focuses the ions as they enter the intermediate vacuum stage, minimizing space charge effects and reducing mass bias.
|
|
لنز امگا -غیر محور طیف سنجی جرمی پلاسما کوپل شده القایی ICP-MS
|
This double deflection lens protects the ORS4 cell and high vacuum region from contamination, by rejecting neutral species from the ion beam. This contributes to the minimal mass bias and low background noise.
|
|
سیستم واکنش زاویه سنج اسپکتروفتومتر جرمی پلاسما کوپل شده القایی ICP-MS
|
The 7900 ICP-MS incorporates a new, 4th generation cell, the ORS4, which provides fast cell gas switching and the most effective interference removal using kinetic energy discrimination (KED) in He mode
|
|
حالت استاندارد سل هلیوم اسپکتروسکوپی جرمی پلاسما کوپل شده القایی ICP-MS
|
Only the combination of narrow ion energy distribution (due to Shield Torch) and the 7900 ICP-MS’s unique octupole -based cell enables efficient removal of interferences using an inert cell gas (He) and KED. The use of He cell gas also eliminates safety issues related to reactive gases such as H2, H2 mixes or NH3.
|
|
سل کنترل گازی اسپکتروفتومتر پلاسما جفت شده القایی جرمی ICP-MS
|
The 7900 ICP-MS has a single He cell gas controller as standard. A second or third cell gas line can be added to permit the use of reactive cell gases such as H2, xenon or ammonia. If multiple cell gases are used in a method, the cell gas is automatically changed with minimal switching time (~5 sec).

آنالایزر جرمی اسپکترومتر پلاسما جفت شده القایی جرمی ICP-MS
|
|
طیف سنج جرمی Quadrupole اسپکتروسکوپی پلاسما جفت شده القایی جرمی ICP-MS
|
The 7900 ICP-MS uses a true hyperbolic quadrupole, unique in ICP-MS, operating at high (3 MHz) frequency. A hyperbolic profile quadrupole provides superior ion transmission, resolution and abundance sensitivity at standard settings, so eliminating the need for multiple resolution settings to separate adjacent peaks.
• Mass range: 2–260 amu
• Mass scan speed:
• Slew rate (Li to U, no intervening peaks): 56.6 million amu/s
• Scan speed (Li to U, plus data collection at 40 intervening masses): >3,000 amu/s
• Abundance Sensitivity (at Cs):
• Low Mass side: 5 x 10-7
• High Mass side: 1 x 10-7

سیستم آشکارساز Orthogonal ( (ODS طیف سنجی پلاسما جفت شده القایی جرمی ICP-MS
|
The ODS delivers higher sensitivity, lower background, and a wider linear dynamic range — up to 11 orders of magnitude from 0.1 cps to 10 Gcps. Fast measurement of transient signals is provided, due to the use of a proprietary analog amplifi er, which operates at the same short integration time (100 μsec) in both pulse and analog mode. There is no settling time between measurements in fast TRA mode.
|
|
سیستم خلاء اسپکتروفتومتر جرمی پلاسما کوپل شده القایی ICP-MS
|
Three-stage differential vacuum system using a single, split-fl ow turbo molecular pump and single external rotary pump for fast pump-down and simple maintenance. Unique Auto recover mode returns the 7900 ICP-MS to standby (pumping) state when electrical power is resumed after a power failure, saving valuable time. No need to manually start the vacuum system following an overnight power failure.
